Time zone offset

Hi all,
Im trying to extract the number of offset hours (from GMT) for a given datetime out of a 'timestamp with time zone' but with no success.
I can't use the function TZ_OFFSET because of DST, the offset is changing acording to DST, and im getting a datetime from all year periods.
select to_timestamp_tz('10/29/2006 01:01:00 gmt', 'mm/dd/yyyy hh24:mi:ss tzr') from dual
returns : 10/29/2006 1:01:00.000000000 AM +00:00
select to_char(to_timestamp_tz('10/29/2006 01:01:00 gmt', 'mm/dd/yyyy hh24:mi:ss tzr')) from dual
returns : 29-OCT-06 01.01.00.000000000 AM GMT
the hours offset has turned into the timezone string.....
Any Ideas?
Thanx,
Anna

I am trying to do the same thing.
I just want to get the hours from GMT of a given time zone, in standard time always, not daylight savings time.
Is there a way to do this?

Time Zone Offset - Date Format question

I'm wondering if any one knows how to display the time zone offset of a date in the following format "[+-]HH:mm." More so... I need the date/time in the ISO 8601 format "yyyy-MM-dd'T'HH:mm:ss[+-]HH:mm", where the last [+-]HH:mm is the hour representation of the offset. Here's some sample code...
SimpleDateFormat sdf1 = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss");
Calendar rightnow= Calendar.getInstance();
// So if system date/time is February 14, 2002 at 1:15:00 PM EST, this would produce "2002-02-14T13:15:00"
System.out.println("Current Datetime" + sdf1.format rightnow.getTime());
How can I get the timezone offset appended to my output in a [+-]HH:mm format. So, the above date needs to look like "2002-02-14T13:15:00-05:00". I can get the offset in milliseconds by doing the following:
int offset1 = rightnow.get(rightnow.ZONE_OFFSET) + rightnow.get(rightnow.DST_OFFSET);
But how can you get this representation into the [+-]HH:mm format?
thanks in advance,
stophman

Try something like this:import java.text.* ;
import java.util.* ;
static public String formatISO8601(Calendar cal) {
     * create ISO 8601 formatter for Calendar objects
    MessageFormat iso8601 = new MessageFormat("{0,time}{1,number,+00;-00}:{2,number,00}") ;
    // need to shove a date formatter that is cognizant of the
    // calendar's time zone into the message formatter
    DateFormat df = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss") ;
    df.setTimeZone(cal.getTimeZone()) ;
    iso8601.setFormat(0, df) ;
     * calculate the time zone offset from UTC in hours and minutes at the current time
    long zoneOff = cal.get(Calendar.ZONE_OFFSET) + cal.get(Calendar.DST_OFFSET) ;
    zoneOff /= 60000L ; // in minutes
    int zoneHrs = (int) (zoneOff / 60L) ;
    int zoneMins = (int) (zoneOff % 60L) ;
    if (zoneMins < 0) zoneMins = -zoneMins ;
    return (iso8601.format(new Object[] {
                                cal.getTime(),
                                new Integer(zoneHrs),
                                new Integer(zoneMins)
}

How get current time zone offset ?

Hi,
I am facing to a problem related getting time zone offset.
Below code is used for my application :
NSDate* sourceDate = [NSDate date];
NSTimeZone* destinationTimeZone = [NSTimeZone systemTimeZone];
timeZoneOffset = [destinationTimeZone secondsFromGMTForDate:sourceDate] / 3600;
But sometimes seems that above code is getting work wrong. For example :
Knoxville, TN : time zone offset should be -5. But my code resulted it as -4.
http://www.timeanddate.com/worldclock/city.html?n=843
This web is related my issue. Here is :
Standard time zone: UTC/GMT -5 hours
Daylight saving time: +1 hour
Current time zone offset: UTC/GMT -4 hours
Actually I don't know how get to "Daylight saving time:".
Can you correct this issue for me ?
Please advice.
Thanks.

Hi Raiden -

I think your code is giving you the correct offset for Knoxville on today's date. The offset for Eastern Standard Time (EST) is -5, but Knoxville is currently on Eastern Daylight Time (EDT), which is one hour later than EST. (-5) + 1 => (-4), which is what your code computed.
Note that [secondsFromGMTForDate:|http://developer.apple.com/library/ios/documentation/Co coa/Reference/Foundation/Classes/NSTimeZoneClass/Reference/Reference.html#//appleref/doc/uid/20000190-CACDIAIC] is correcting for daylight savings time. That's why you need to pass the date to that method. If you pass a "summer" date, the return offset will be one hour more than it will be for a "winter" date (usually early November to mid March). For example, try moving the date forward 60 days like this:
NSDate *sourceDate = [NSDate dateWithTimeIntervalSinceNow:3600 * 24 * 60];
NSTimeZone* destinationTimeZone = [NSTimeZone systemTimeZone];
int timeZoneOffset = [destinationTimeZone secondsFromGMTForDate:sourceDate] / 3600;
NSLog(@"sourceDate=%@ timeZoneOffset=%d", sourceDate, timeZoneOffset);
The above should give you the offset for Knoxville on Dec. 7, 2010, which is a winter date.
Actually I don't know how get to "Daylight saving time:".
You can test a NSTimeZone object with [isDaylightSavingTimeForDate:|http://developer.apple.com/library/ios/documentat ion/Cocoa/Reference/Foundation/Classes/NSTimeZoneClass/Reference/Reference.html#//appleref/doc/uid/20000190-CHDCJGHE], but you don't need that information when you obtain the offset with secondsFromGMTForDate:.

Retrieve System Time Zone Offset?

Hi, I'm doing some GPS emulation and need to retrieve the system Time Zone Offset in (Hour and Minute). For example if Mountain time zone offset hour = -7 and Minute = 00. Is this information possible to get in Labview?
Thanks.

Hello QRP,
Yes, it can be done, but this way is not very elegant. It will get the GMT offset that your PC has as its current setting.
Use Format Date/TIme String with a format string of "%z". The output is the offset as a STRING formatted HH:MMS
Break the string apart with Scan From String to get the individual elements, or by using "%t" as the format, get the offset in seconds.
Rod.
EDIT: There shouldn't be a smiley in the time format above, It's "HH : MM : SS" but ignore the spaces!

Customising SYSDATE using time-zone offset

Situation:
A database instance is configured with multiple schemas with each holding data for a company. A set of Oracle Forms and Reports programs has been developed to run against each of these schemas.
However, there are few overseas companies phyiscally located in different time zone with respect to the database location.
Is there a way to "customise" sysdate to generate "adjusted" date/time value using the time zone offset "without changing the programs" (in Forms, Reports and dbms)? Most of the programs use sysdate to populate date-specific fields.
Please advise.
Thanks

Sysdate is sysdate-- it can't be changed on a session-by-session basis. You could write your own sysdate-like function, but that would require code changes. If you are making code changes, and you're on 9i, I would suggest using a TIMESTAMP WITH TIMEZONE data type.

How to remove time zone offset when we use a number as a relative time variable?

Hi everyone!
I've a small doubt in using a number as a relative time. If I change the display properties of a numeric to relative time, it takes default value "5:30 AM", may be because I'd set time zone to Indian time during installation ( India is 5:30 hours ahead of Greenwhich). I want it to take default value "12:00 AM'. Please help me how I do it?
( I can also subtract 5:30 hours and get the same. But I want that to have "12:00 AM" by default......?!)
Thank you all..!

As Ravens already stated, you are using ABSOLUTE time. Relative time can only be set to display hours, minutes, and/or seconds.

Databases for Multi Time Zone

We got two different SQL Server which are running SQL Server 2008 R2 and soon we are upgrading to one SQL Server 2012. Both are running in different time zone
I been given a task that whether is it possible to publish databases on One Server with different Time Zone( just to reduce the cost).
we got 1000+ SP's which uses Getdate() and GET date UTC function.
My Question is that, is it possible to publish databases on a single server with multi Time zone and if yes then how do i manage those.
Thanks

Hi,
Agree with the previous comments. The workaround is to use SWITCHOFFSET() function to calculate the time based on a time zone offset.
The following example uses SWITCHOFFSET to display a different time zone offset than the value stored in the database.
CREATE TABLE dbo.test
ColDatetimeoffset datetimeoffset
GO
INSERT INTO dbo.test
VALUES ('1998-09-20 7:45:50.71345 -5:00');
GO
SELECT SWITCHOFFSET (ColDatetimeoffset, '-08:00')
FROM dbo.test;
GO
--Returns: 1998-09-20 04:45:50.7134500 -08:00
SELECT ColDatetimeoffset
FROM dbo.test;
--Returns: 1998-09-20 07:45:50.7134500 -05:00

Browser Time Zone Setting

We're using Apex 4.x and I need to capture the Browser Time Zone (TZ) into an application level item. Can anyone please suggest the approach.
Initial thoughts are to capture the TZ using JavaScript and use it inside the Page 101 login procedure. But, I'd appreciate any tips on how this TZ can be passed into an application level item and stored for further usage within my application.
Thanks,
VS Kumar

Jari - Thanks for your great tip. I was able to utilize this feature and assigned to apex application variable the timezone offset using GET_SESSION_TIMEZONE. I have a minor issue since I'm setting in the apex developer menu path - 'Shared Components ->Edit Globalization Attributes ->Automatic Time Zone=Yes'
When I run the application there is a brief 5 seconds *'Set Time Zone'* message that pops and then I see the login. Do you know how this message can be not visible, but still be able to set the session time zone offset using the above setting (Meaning, the problem is fixed using the above setting, but the message that appears before the login screen appears 'Set Time Zone' is a bit inconvenient.
Can you please advice if this message can be made NOT to display, but continue to use the 'Yes' for 'Automatic Time Zone' in the Globalization Attributes?
Thanks,
SK

Session Time ZONE

Hi ALL,
Can you please suggest on this, how to do this:
If I run queries in my machine:
select sessiontimezone from dual
I get “+05:30”
And formula
select
to_number (substr(sessiontimezone,1,1) || '1') * (to_number(substr(sessiontimezone,2,2))+ to_number(substr(sessiontimezone,5,2)) /60) /24
from dual
Gives “0.229166666666667”
But when we are running same queries on Amit Rathore’s machine it is giving us
select sessiontimezone from dual
“Asia/Calcutta”
And error in formula
select
to_number (substr(sessiontimezone,1,1) || '1') * (to_number(substr(sessiontimezone,2,2))+ to_number(substr(sessiontimezone,5,2)) /60) /24
from dual
“Invalid Number”
Could you please suggest how we can change sessiontimezone to return hours and minutes (“+05:30”) in other machine?
Regards
Girish Sharma

SESSIONTIMEZONE returns the time zone of the current session. The return type is a time zone offset (a character type in the format '[+|]TZH:TZM') or a time zone region name, depending on how the ?user specified the session time zone value in the most recent ALTER SESSION statement."
The default client session time zone is an offset even if the client operating system uses a named time zone. If you want the default session time zone to use a named time zone, then set the ORA_SDTZ variable in the client environment to an Oracle time zone region name.

How do I set a time zone not in the standard list?

I would like to set my time zone to Lord Howe Standard TIme(LHST), which is GMT +10:30hrs. How do I do that? How do I check that the standard time servers know when to change for daylight saving time?
Regards, Rob

ozRob wrote:
1. I have to log out and back in for the change to take effect in system preferences and the clock
I did warn you about this ("This change will not show up in the Menu Bar clock until you have logged out and back in"), although when I did it the change was reflected in System Preferences immediately. To reset the clock without logging out,
killall SystemUIServer
You can do this while you are still root, i.e. before the exit statement, or after it.
2. Lord Howe is the only place listed in the "closest city" list
Well, that's because it isn't in the Preference Pane's list of places so it cannot compute distances.
3. If I click anywhere on the world map, the time zone changes to whatever I clicked on and I have to follow your instructions, then log out and in again, to get back to Lord Howe time
The obvious answer is don't click on the map!
I can't understand why Apple hide this stuff. I think there should be a way to manually set the time zone offset as well as daylight saving start and end dates - we aren't all idiots. At the very least they should make all the time zones in the zoneinfo directory available, perhaps under a checkbox marked "rare zones" or similar.
Well, I suggest you send Apple Feedback about this.
Thank you all for your efforts, if anyone can solve the issues above I'd be very grateful.
Actually the changes to add Lord Howe are relatively trivial, if you know what you are doing. One complication is that "Lord Howe" would have to be added as a localizable string: don't know what might happen if it were missing. I'll play around some more, but don't hold your breath!

Outlook Client recurring appointments time zone / GMT offset problem

I will try to describe this with text, although it's a very visual problem. I added a post to my blog with
it so I could include pictures. If you think you need pictures to understand the text below, please review that entry.  Please note, the one appointment instance cited below, is an example, there are many others with this same problem,
and it only happens with recurring appointments.
Relevant System Information:
Windows 7 Utlimate
Office 2010 Professional Plus (14.0.6023.1000 64-bit)
Exchange services hosted by Microsoft.
Android HTC Inspire 4G also configured as exchange active sync client.
Issue Description:
I have a specifications meeting that is scheduled for Tuesday mornings (every 2 weeks) at 8:30 am. In the body of the appointment, it even has this text spelled out. "When: Occurs every 2 weeks on Tuesday effective 11/23/2010 from 8:30
AM to 11:30 AM (UTC-05:00) Eastern Time (US & Canada)." as an indicator of the actual appointment time. The problem is that one day, several weeks after this appointment had been sent to me, Outlook 2010 decided that it was really at 1:30 PM.
Since that time it's been showing incorrectly on my calendar at 1:30 PM.   So, I recognized almost immediately that this was a 5 hour difference, which happens to also be my timezone offset (except that I'm currently in daylight savings time -- so
it's really a -4 offset right now).
I ran the 2010 service pack 1 installer, based on the suggestion of my IT group, and found I already had the service pack installed. I've tried the timezone tool as well and that didn't work. Please keep reading.
Next I went to my exchange host with outlook web access.   The appointment is closer to correct there, showing at 9:30am. It think here it almost seems as though it's applying the DST, but not correctly, maybe doubling it?.
Meanwhile, back in outlook, if I go to the scheduling assistant and look at my time while making an appointment with other invitees it - much to my surprise - matches the time in OWA, not the time in outlook client.
Finally, if I go to my Android and look at the appointment, it is correct. 8:30 AM.
So to summarize:
Real Appoinment:   8:30 AM
Outlook Client Time: 1:30 PM
OWA / Exchange Time: 9:30 AM
Android Calendar Time: 8:30 AM
This applies to many others, this is just a convenient example.
This applies only to recurring appointments.
Any help would be very appreciated.
Thanks,
Jon

Status Update, and recommended next steps:
I opened a ticket with HTC support the day before yesterday (Ticket # 03543601). The initial response was an email reply with the typical level one suggestion to remove and re-add the Exchange ActiveSync account on my phone, and if that didn't resolve the
issue to do a hard reset and then add the account again. Since I have multiple users experiencing this same issue, where the common denominator seems to be centralized around the move from Outlook 2007 to 2010 and the HTC Gingerbread OS, I convinced them that
this would not be an acceptable remedy, and my case was immediately escalated without hesitation. I will say that though I don't have a resolution, I'll applaud HTC for not giving me the runaround and giving me a live person who could talk intelligently about
the issue.
Today, I received a phone call back on this ticket from someone in the escalations department at HTC named Travis. After explaining the issue in detail to him and referencing
this specific thread, he acknowledged that it did in fact sound like a coding issue coming from the device where the value in the “dispidApptTZDefStartDisplay” property was being set improperly by the device/stock email/calendar application in their implementation
of ActiveSync. He then stated that he would relay this to the developers to look into the issue. He further elaborated that the case would either be in a status of, "this is being looked into", or "We believe this to be resolved in [x] update". He said that
they will probably continue releasing updates for the Incredible (I did not specifically ask about the Incredible 2), and while the Incredible 2 is definitely slated to get Ice Cream Sandwich, the Incredible one is still in a classification of, "being evaluated".
Personally, I doubt that the Inc 1 will get ICS, but it is possible. From what I have read, the general stance is that phones will be updated for 18 months after release, and the Inc 1 is 24 months old this month (bummer - I REALLY like this phone).
According to Verizon and HTC, these are the phones that will get ICS (or Android 4.0):
Ice Cream Sandwich Coming to Many Verizon Wireless Smartphones
Android 4.0, Ice Cream Sandwich Updates
While it is possible that an update will be released for the Incredible 1 to fix this issue, it will likely be months before one is available, so we'll probably have to move to Touchdown for Exchange by NitroDesk in order to resolve this issue....or move to
a newer phone with ICS 4.0.
Speaking of which, there is a whole laundry list of issues with Exchange ActiveSync and third-party devices. A number of them are listed in this Microsoft KB article:
Current issues with Microsoft Exchange ActiveSync and third-party devices
Per the article:
Microsoft's recommendation for Android - Upgrade to Android OS 4.0
Microsoft's recommendation for iPhone/iOS devices - Upgrade to iOS version 5
So, for anyone on Android experiencing this issue (or others listed in the Microsoft KB above), if your phone is likely to get ICS soon, then you may want to hold on and just be vigilant about checking your calendar on OWA. If your phone isn't slated to get
ICS or if you can't wait, my recommendation is to get Touchdown for $20. You may still have to delete and re-create appointments that are wrong, but hopefully the issue won't happen any more once you move to Touchdown. And if they do, at least you've got a
shot at a more rapid fix with a company like NitroDesk. (no offense HTC).
Good luck. I probably won't post again unless I get notice of a fix for this specific issue or some other significantly useful information.

Incorrect time offset settings for Russian time zones

I'm putting new USC blade servers to production. I've discovered that if I set correct time zone for my city ( "Asia/Yekaterinburg (Moscow+02 Urals)" ), the time shown in USC Manager is one hour behind the actual time. It seems that this bug is related to any Russian time zone. For example, if I select Novosibirsk time zone (Asia/Moscow+3), the system shows correct time for my city, which is one hour behind Novosibirsk time.
USC Manager version is 2.1(1a) (the latest version available for download from Cisco site). The system is set to obtain correct time from NTP server which is local Windows domain controller (which, in turn, syncronizes its time from Internet NTP server).
Switching between summer and winter time in Russia was cancelled two or three years ago. I suspect that Cisco programmers are simply unaware of this fact.

Hi Evgeniy,
We had a bug filed for this and this was supposed to be fixed in 2.1 release.
http://tools.cisco.com/Support/BugToolKit/search/getBugDetails.do?method=fetchBugDetails&bugId=CSCtw92688
Let me check in my lab as well and check with the engineering (if required) and communicate back to you.

The offset +0400 is absolutely wrong!
Since I see in convergence all events shifted by one hour back respect to lightning data.
I found a lot of information about how to add time zone alias, but have no info about correction existing time zone.
Any comments are welcome.
Thank you, Monk.
P.S.
Operating system time zone information is right.
Java time zone is updated too.

Yes I know about time zone information into VEVENT Object.
Can You provide me URL where I can download plugin you are talking about?
Plugin can be for Firefox or Chrome.
Till now I can only use export calendar button of Convergence Calendar interface.
Here you can find two event
th-17 and th-19 created by Lightning
th-17 - started 17-00
th-19 - started 19-00
According to the Convergence them start at 16-00 and 18-00 respectively.
By the way .Lightning show them correct but fire alarm one hour earlier.
15-45
17-45
Seams that Lightning took wrong time zone information from the server with +4 offset.

How do I set and use a custom time zone?

We're developing a mixed HTML, javascript and Flex application.
In our HTML/Flex application, one of user's settings is the time zone he wishes to use. Since this can be different from the local time zone of the computer he happens to be using, we need to tell flex to interpret all dates as being in a foreign time zone e.g. force it to America/Los_Angeles.
I'm hoping there is a way to specify this in flex, so we don't have to do offset calculations on every single Date object. This would be very complicated, as I'm sure you know (and no, it is not simply UTC + x, where x is a constant, or x is an integer number of hours...)
Is there a way to do this in flex?

P.S: I've found these related things so far:
asTimeZone: The svn repository is 404, and there seems to be no activity, but looks interesting...
A reference to the system class, but I couldn't find anything interested in the system class.
A comment that player 10 should have something useful, but I didn't find any thing about it elsewhere.
But nothing was really helpful...

Oh, perhaps this isn't possible, according to Timezone Issues with remote (Date/Time) data and flash
But if you have knowledge of a way to do it, please let us know here.
