All-day calendar entries and daylight savings time

Since changing to daylight savings time, whenever I change the date on an all-day calendar entry, my iPad (but not my iPhone) changes the one-day calendar entry to a two-da calendar entry. How do I correct this?

Dates are represented internally with a long that represents the number of milliseconds past some fixed point. Timezones do not affect this.
I'm assuming you're getting your dates as java.sql.Date
You should then build a Calendar (see GregorianCalendar) and call setTimeZone() with your timezone without daylight savings

Since downloading iOS 7.3 I have lost all my calendar entries and it wont accept new entries. Is it me or the system?

Since downloading iOS7.3 to my iphone 4, I have lost all my calendar entries and it won't let me create new entries either. Is it me or is it the system and if the latter how do I recover the data and add to it?
I am not up dating the system on my ipad in case the same thing happens. They aren't syncing on this facility.

Easy solution, thank goodness. On your iPhone, go to settings, then to iCloud. If your Calendar selection is turned off, turn it on. Your info should restore. If your Calendar selection is turned on, then turn it off. Choose to save calendars when asked. After it shuts the Calendar off, turn it back on. Your info should be restored.
Thank you to Apple support for walking me through this. Shame on you Apple for not just telling people about this easy fix rather than making us go through all of this pain and worry.

Has anyone had problems in v5.0a of Iplanet calendar installed on a Sun box with creating events and daylight savings time?

Events created around 4/6/2002 at 8pm get created with the wrong time (9pm) and there are several other creation and display problems tied to Daylight Savings in April and October. Version 5.1 of the software seems to fix that but we are looking for a fix until we can upgrade. We have been using Windows systems to access the calendar.
Thanks.

We have not seen exactly this, but many users appointments are lining up in the wrong time slots. Also, when scheduling, the time display is off by an hour. We have found what looks like a temporary fix.
We noticed that the problem only affects users who have the start of the week set to Sunday (when daylight savings time started). Setting the week to start on Monday fixed our display problems (you can do it in the users, options section).
I am placing a support call w/SUN.

E-Load/e-ME and Daylight Savings Time Change

If you are using e-TEST suite versions 8.10 or older, please see the following knowledge base article on updating your JRE for e-Load and e-Manager Enterprise.
http://qazone.empirix.com/entry.jspa?externalID=201&categoryID=15
(you must be logged into QAZone to view this link)
It is recommended that e-Load and e-Manager Enterprise customers update the JRE on their e-Load and e-ME server machines using the SUN JRE patch referenced in the article.
e-TEST suite version 8.20 which is releasing this week does not require any update.

Issue with All Day events - post Australian Daylight Savings change.

Hi all,
I have had a weird problem occur since daylight savings has changed for Australia.
I sync my Microsoft Outlook 2003 on my PC and calender on my iPhone. This works great and I have never had a problem until now. Since Sunday, 'all day' events created on Outlook are going into the previous day on the iPhone, and any 'all day' events created on the iPhone are spread across two days on Outlook.
All the timezones and clocks are correct on both devices and any specifc time appointments are correct on both devices. This only applies to All Day Events.
The other strange thing is that it only occurs for days between now and the last weekend in October. Interestingly enough this was the old date of daylight savings changeover before it was brought forward in 2007.
I think what is happening is that the iPhone's timezone doesn't know that it is daylights savings yet, even though the cell network is updating the clocks and making it appear correct.
This is also happening to my colleague.
Not sure how to fix this. Surely this is happening to others.
Any help would be great...

i noticed with a client and outlook, when syncing with m.me i had a similar problem where i made an all day event and vs 1 day it was two.. the problem was tracked down to how outlook makes the event; it made a '24 hr event' not an 'untimed' event.
I unchecked the 'all day even't and it showed the event going from midnight to midnight (which for no good reason it called that the next day which it is not).. I shortened up the duration to a few hours mid-day and then checked the 'all day' check and it made it one day again.
post if it works.

CF MX and Daylight Savings Time Change

Next year 2007, the Daylight Saving day (chaning the clocks
for spring and fall) will be changing. The Spring date will be a
month earlier and the fall date a month later then it has been for
years.
How will the Cold Fusion Server for MX 7+ handle this? Will
it use the server time or use the internal CF Server clock?
Thanks.

My problem is that now CFMX 6.1 thinks that it is 8 hours
later in the day
than it really is (it is stuck on GMT now) and I am unable to
get CFMX to
acknowledge the operating systems clock. :-(

SimpleDateFormat and Daylight Savings Time

I am trying to parse into a Date "April 15 1999" with "MMM d YYYY" using SimpleDateFormat. This string parses w/out error and the resulting Date is: Thu Apr 15 00:00:00 PST 1999. This is correct in that I am in California. The problem is that 4/15 is Daylight Savings Time in 1999. The getTimeZone result for the parent DateFormat is "SystemV/PST8PDT". I have wrestled with this for over a day now, I admit it, I need help.
Anyone have any ideas what could be happening here?
Thanks
Roger

When I run BigDaddy's code I get MST for the TZ (which is correct, my default is Mountain TZ and we don't observe DST. By this I surmise that BDLH's default is Pacific TZ and that it observes DST. The following code shows the setting of the TZ to "America/Los_Angeles" and produces the correct result. Windows XP.
import java.text.*;
import java.util.*;
public class PTest {
    public static void main(String[] args) throws ParseException {
        SimpleDateFormat sdf = new SimpleDateFormat("MMM dd yyyy");
        Date dte = sdf.parse("April 15 1999");
        System.out.println(dte);
        SimpleDateFormat sdf2 = new SimpleDateFormat("MMM dd yyyy zzzz");
        sdf2.setTimeZone(TimeZone.getTimeZone("America/Los_Angeles"));
        System.out.println(sdf2.format(dte));
}

CF MX and Daylight Savings Time

Hi. We have ColdFusion MX Version 6,1,0,83762 installed on
our Windows 2003 server. Will we have any issues with the product
and the Daylight Savings Time coming up on March 11? Is there a
required patch for this change? Thank you.

CUE timezone and daylight savings time

Hi,
Having issue where CUEs don't seem to be adjusting for daylight savings time. Timezone is set correct to EST but is a hour off because its daylight savings time now. The router and CUE are configured to use same NTP server and router has summertime setting and adjusts for DST fine and has correct time but CUE is a hour behind, like it is not doing DST.
Were on version 2.2(2) of CUE software.
This is also in indiana where the laws changed recently so maybe that has something to do with this.
Any ideas?

Very likely due to the change in Indiana. A workaround would be to change the timezone to an EST zone that observes DST such as America/Louisville (Eastern Time - Kentucky - Louisville Area).
Hope this helps.

COREid and Daylight Savings Time for 2007

Do COREid or any of its components require any special fix in order to comply or function properly with the new Daylight Savings Time for 2007?
Background:
In August of 2005 the United States Congress passed the Energy Policy Act,
which changes the dates of both the start and end of daylight saving time
(DST). When this law goes into effect in 2007, DST will start three weeks
earlier (2:00 A.M. on the second Sunday in March) and will end one week later
(2:00 A.M. on the first Sunday in November) than what had traditionally
occurred.
Thanks,
Craig

We have experienced many problems with DST and COREid in the past; most of them resulting in hung Access server and unavailability. I don't know if it's because we have components distributed across multiple time zones or what. Our plan is to have someone available at the time change to cycle the services (and maybe the server as a whole) and do a health check after the fact. I hope this helps.

Energy Act of 2005 and Daylight Savings Time

We currently use Sun Studio compilers. We use the embedded tools.h RogueWave libraries. The Energy Act of 2005 changes the dates for Daylight Savings Time starting in 2007. Will there be any patches from Sun to handle this? We currently use RWZoneSimple which is extensible, but we were hoping for an update from Sun.
Thanks in advance. Sorry if this has been covered, I just couldn't find anything.
Further Reading:
http://en.wikipedia.org/wiki/Energy_Policy_Act_of_2005

The RW Tools.h++ library that comes with Sun Studio has been updated with the new DST rules. I don't think the patches have been released yet.
If you have a service contract with Sun, you can get a pre-release version of the patch via your support channel.
Otherwise, check the Sun Studio patch page from time to time
http://developers.sun.com/sunstudio/downloads/patches/index.jsp
Look for a C++ compiler patch that includes a fix for bug 6456479.
RW Tools.h++ does its own DST calculations. Other libraries rely on the Solaris functions in libc. Patches for Solaris are available now as follows:
S10 - 118833-24(sparc), 118855-19(x86)
(The fix is included in S10u2.)
S 9 - 112874-34(sparc), 114432-24(x86)
S 8 - 108993-62(sparc), 108994-62(x86)

Calendar and Daylight Savings Time

I'm trying to use Calendar objects to store month, day, year information for use in date comparisons/calculations. (e.g. how many days between 1/1/06 and 2/1/06) My program knows nothing of hours, seconds, minutes, etc. and it really doesn't care about them.
That being said, the concept of hour has been cropping up since Calendar automatically throws in an extra hour here and there for DST. In very specific circumstances it can cause an incorrect value.
So to solve this I decided to turn off DST but that seems to be more complicated than it should be. My solution was to create a SimpleTimeZone that has DST disabled and use that as the time zone in my Calendar. Unfortunately, this doesn't work. It now subtracts an hour every now and then (for some strange reason).
So is there any way I'm not seeing in the API to just simply disable DST?
Thanks in advance.

Ok here's a minimal example of what I'm taking about:
import java.util.GregorianCalendar;
import java.text.SimpleDateFormat;
public class Test {
     public static void main( String[] args ) throws Exception {
          SimpleDateFormat format = new SimpleDateFormat( "MM/dd/yy" );
          format.setLenient( false );
          GregorianCalendar testCal1 = new GregorianCalendar();
          testCal1.setTime( format.parse( "10/29/2006" ) ); //One day before DST switch
          GregorianCalendar testCal2 = new GregorianCalendar();
          testCal2.setTime( format.parse( "10/30/2006" ) ); //After DST switch
          long time1 = testCal1.getTimeInMillis();
          long time2 = testCal2.getTimeInMillis();
          System.out.println( time2 - time1 );
}The output of the program is 90000000.
Using some basic math you can calculate that the time between a single day should be 86400000 milliseconds. The difference between the result and the theoretical time between two days is exactly 1 hour.

Oracle TimeZones and Daylight savings time

Hi,
I am working on converting a bunch of old data to a new system. I ran a couple of validation reports for the end user to verify, it seems the times were off. I am in the EST but it seems the times in the db were stored as UTC.
So when you convert the time from UTC to EST you need to subtract 5 hours but when it is DST you only subtract 4.
I need to know how to figure out if a time was entered in DST or EST and then I can use something like a decode to decide how much to subtract.
DST Rules:
Stone Age -- 2006 First Sunday in April ,Last Sunday in October
2007 -- present DST Begins 2 a.m. (Second Sunday in March) DST Ends 2 a.m. (First Sunday in November)
Here is part of my select statment:
to_date(to_char(asgn.start_date-5/24,'DD-MON-YYYY')) effective_from,
I looked at Ask Tom and other sites but could not find a good working example that didn't have a hard coded date. Maybe it is not possible in a select statement.
Thanks so much for any help you can provide !!!! :)

This seemed to do it:

I don't see how it possibly can. A DATE datatype does not contain timezone. See the definition of what it contains in the SQL Language doc
http://docs.oracle.com/cd/B28359_01/server.111/b28286/sql_elements001.htm#i54330
>
12
DATE
Valid date range from January 1, 4712 BC, to December 31, 9999 AD. The default format is determined explicitly by the NLS_DATE_FORMAT parameter or implicitly by the NLS_TERRITORY parameter. The size is fixed at 7 bytes. This datatype contains the datetime fields YEAR, MONTH, DAY, HOUR, MINUTE, and SECOND. It does not have fractional seconds or a time zone.
>
So that DATE value has NO way of knowing what the timezone of the process that entered it was.
And depending on the meaning of that DATE column you don't even know for sure if the date value represents a date in that process's timezone. I can enter a date representing '01-Jan-2007' but that date doesn't necessarily mean it belongs to my timezone.

I tried to sync Outlook 2011 with iCloud and it deleted all my calendar entries and now are only on iCloud and I cant figure out how to export them back to Outlook. Can anyone help me?

I signed up for iCloud today and tred to sync my Outlook 2011 calendar with it. At first, all the entries were completely deleted from Outlook but were still in iCal. Then I attempted to export my iCal events, turn off iCloud for calendars and import the iCal info to Outlook. But since it was only synced through iCloud nothing imported... now all my Outlook info is only on iCloud.. can anyone help me get it back on Outlook?
