DST (Daylight Saving Time) for WLSE

Does anyone know if there is going to be a patch for the DST change for the WLSE, or if there is just a way to change it command-line, what that would be.
Thanks,
Pat

The ONS 15302 supports time protocol (RFC 868) for automatic date and time adjustment. To utilize this feature a TP server must be available in the network.
Because the time protocol provides UTC (GMT) only, and does not take into account the Day Light Saving Time (summer time), an additional parameter (UTC Delta) allows the user to get the local time. This parameter must be adjusted twice a year to take into account the Day Light Saving Time

DST Daylight Saving Time

I am using Solaris 9 on Sun hardware. I have set the Time Zone as Asia/Karachi. I dont know how the Daylight Saving Time is enabled with this setting. I just want DST to Trun Off. How can I disable DST for my zone?

Thank you for all the reply. Finally, I've solved the problem. For Tunisia there is no DST according to this page: http://www.timeanddate.com/worldclock/timezone.html?n=253&syear=2010
So, I did the followings:
# vi /usr/share/lib/zoneinfo/src/africa
I modified the rules according to the following:
Rule Tunisia 2006 2008 - Mar lastSun 2:00s 1:00 S
Rule Tunisia 2006 2008 - Oct lastSun 2:00s 0 -
Finally I run the following command:
# zic /usr/share/lib/zoneinfo/src/africa
It is solved my problem!

What is the best way to switch off Daylight Saving Time?

What is the best way to switch off Daylight Saving Time for a DST enabled timezone?

I've been looking through the related classes and can't seem to find a way to disable DST in any timezone. Probably because they couldn't think of a good reason to want to know what the non-DST time was during DST.
However, you could easily compute the time without DST if that's what you need.

Exchange Active Sync UTC Daylight Saving Time

Color me a bit confused. I am attempting to write an IOS client application to communicate with Exchange ActiveSync and display calendar information. But I am seeing some conflicting information in the protocol docs when compared to what I am getting from
Exchange. Either that or I am somehow misinterpreting one or the other.
My intent is to save an appointment in my local database in Coordinated Universal Time and then have the UI read in the information and display it as appropriate to the local timezone. In this way an recurring appointment created before daylight saving time
for Noon will still be at the same time of day in local time as an appointment created during daylight saving time for noon. But they are not.
My understanding of the documentation is as such:
In MS-ASCAL pdf section 2.2.2.40 (roughly page 34) it says for Start Time that : ...the value of this element is a dateTime data type as specified in MS-ASDTYPE section 2.3.
Moving to MS-ASDTYPE section 2.3 (roughly page 7) the dateTime value is specified in the format of ISO-8601 and all dates are given in Coordinated Universal Time (UTC)
Looking up coordinated universal time I see that UTC does not changed with the seasons as local or civil time does and therefore DOES NOT support daylight saving time. This makes sense, as DST is decidedly local and is ignored by many areas. You cannot know
from the perspective of UTC whether or not to apply a DST offset without knowing what timezone and area the time represents, therefore no daylight saving time can be supported. Based on this information I should be able to just slap the dates into my database
as they are and merely have the UI adjust itself to display them properly.
However, as a tested I began seeing a divergence of an hour between the two appointments in the database before the UI has even read them. To confirm this I created two recurring appointments representing Lunch at 12 noon local time. One that starts on March
1st 2014 (Standard Time) and one that starts on March 10th 2014 (daylight saving time) in the eastern timezone. This should be March X 2014 at 1700 hours in both cases should it not?
In the WBXML/XML that I am receiving I am getting two different times. The appointment that starts during standard time gives me a start time of 20140301T170000Z. The appointment that starts after daylight saving time is in effect locally gives me 20140301T160000Z.
The difference between the two times is 1 hour, which is the daylight saving time offset. It is my perception based on everything that I have read both in the microsoft protocol documentation and outside it that these two times should be the same and that whatever
client that gets to display them should be the one putting the offset in place as needed. Noon local time is noon local time but local time is the province of the local municipality/timezone, not that of UTC.
So my question is what exactly is going on here? Are the start/stop/date stamp date times in UTC or not. If they are in UTC, then why are they offset by an hour instead of being at the same time? Obviously outlook displays these correctly for local time,
because both appear at noon. But in my case my database contains locally adjusted times instead of the UTC times I thought I was getting which is throwing off when those appointments appear in the UI.
Can someone please clarify what's going on here and what I should be seeing?
Thanks.

Thanks for the reply, however after doing what is said the problem still remains. I did not try the manual approach, because of the time that would take with calendars that change at least daily.
I am running the latest update of ICal and IPod, you would think this would have been addressed with one of the updates to allow the sync to work correctly with 5th generation IPods.
I am going to try and turn off day light savings time set the clock to a Central Time zone and see if that works, I do not cross time zones much, anymore.

Does BOXI 3.1 supports Daylight Saving Time (DST)?

Hi ,
Can any one tell me whether BOXI 3.1 supports Day Light Saving (DST), in case of scheduling reports?
Thanks in Advance,
Raghuveer.

Hi Reddy,
you can contact your vendor regarding this information ....
You need to appy the Business Objects patch, you will need to apply the extended Daylight Saving Time (EDST) patches for your operating system and Java Virtual Machine and Application Servers in order for the Business Objects patches to take effect. Please contact your vendors for updated information.

Daylight Saving Time Changes for 2007

Hello Friends
Sun's J2SE 1.4.2_11 has taekn care of the new Daylight Saving Time changes in accordance with The Energy Policy Act of 2005. Does anyone know if bea has incorporated same changes to their Jrockit, if so then starting which version.
http://java.sun.com/developer/technicalArticles/Intl/USDST/
Thanks for the answers in advance.
Regards
Rajeev Bhogal

Hello All
We currently compile and run our application with Jrockit 1.4.2_04 (build 1.4.2_04-b05), if we change to minor version 11 for 1.4.2 should we recompile the application. I would think that DST related binaries would only be called at run time not compile time, however I am far from being a compiler expert. Can any learned friend shed some light.
Henrik what do you think.

Daylight Saving Time Changes in 2007 for USA

Can anyone give me solution how to handle Daylight saving Time changes in 2007 in USA for JDK 1.3.x releases? We are using this due to some vendor dependency. We can�t upgrade to higher versions up to middle of the 2007. I would be thankful if somebody gets back to me.

I have a similar issue where we cannot upgrade the jdk 1.1 without involving a lot of effort. If we keep the same old jdk, can someone tell me if use of Date and Calendar api will be impacted by the Daylight saving change.....provided the timezone is default and not explicitly set to EST. Also there isnt any timezone related buss logic.

Support for US Daylight Saving Time changes in 2007

The Start and Stop dates for Daylight Savings Time in US will change from 2007.
From Sun's bug database, it looks like Sun has handled this Daylight Saving Time changes in JDK 1.5.0_06.
http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=6317178
Does anyone know if they have handled this in earlier JDK releases (1.3.x, 1.4.x)? If not, do they have any plan to handle these changes?

1.3.1_18 had a timezone change.
http://java.sun.com/j2se/1.3/ReleaseNotes.html
1.4.2_11 had some timezone changes (but now there is a 1.4.2_12, so use that).
http://java.sun.com/j2se/1.4.2/ReleaseNotes.html
Not sure exactly what the timezone changes were, but check the release notes or give those JDKs a try.

Any patch for US Daylight Saving Time 2007

Do anybody know which Patch of Oracle 9i and 10g will solve US Daylight Saving Time issue 2007

Version 4 is the latest version of the time zone file. It is not available on all platforms yet. Check patch 5632264 to see if it is available for your platform.

Cisco ISE 1.2 Daylight Saving time

Does ISE support DST change?

Time Zone = UTC is best practice for a distributed deployment. Also, remember that if you change the time zone on an ISE, the database is deleted! So, set this during initial setup. BTW, for the Eastern Time Zone in the United States, use EST5EDT in order to allow for Daylight Saving Time.

Daylight Saving Time Patch in 10.2.0.4

Question:
When you apply the 10.2.0.4 patch (linux-64 bit), does this patch include the daylight saving time patch that needed to be applied in earlier releases?

I know that. I was looking for the readme file but my metalink account did not have access to it. I was hoping that the forum would fill in the gap for me.
In this situation, I should have installed the 10.2.0.1 database, then the DST patch and then the 10.2.0.4. Instead, I got ahead of myself and did the 10.2.0.4 patch first. I was just wondering if the DST patch was included in the 10.2.0.4 by now. The good news is that I had my metalink updatred so I have access to the readme file now. I'm glad you knew the answer. Oh wait, you don't.

CreateODBCDateTime monkeys with Daylight Saving Time!!

If one uses CreateODBCDateTime to convert a date into the
proper format for storing in a SQL Server database, and one runs
this operation on a date between 0200 and 0300 on the day that
Daylight Saving Time changes, the function will change the time
forward or backward one hour. IT WILL DO THIS EVEN IF THE DATE YOU
ARE STORING IS UTC, thus rendering UTC times INVALID because they
do not have DST. Why does this function monkey with DST at all?

I have several international web sites on this server, one of
which has over 100,000 users who have contributed over 70 million
records, all with UTC timestamps. The problem occurs during the one
hour period EVERY YEAR when daylight saving time is started. It
does not do this in the fall when the time reverts. So, yes, the
problem only occurs during 1 hour out of 8,760 hours, but when you
start with 70 million records over 5 or 6 years...
But the danger is for anybody who stores or manipulates a
date/time OTHER THAN the date/time that is being used internally to
the server. In other words, if your server is set to Central Time,
and you have users in Hawaii or Arizona who need to store their own
date/time, it is likely to apply Central Timezone RULES to that
date/time, even if Hawaii and Arizona don't use DST.
Let's say you're scheduling operating rooms in a hospital in
Honolulu. All the CF routines are going to make sure to shift those
times forward an hour without warning, have a nice day. In my case,
it is happening with UTC, but it could be ANY time zone that has
different rules than the ones on your server.
Yes, I can probably figure out a different way to process
times, but this is a massive system with thousands of different
templates. In fact it affects several pretty massive software
systems with millions of lines of code, so it's not as if I can
just change a few SQL queries and be done with it.
It probably should be a rule for anybody operating a
ColdFusion server in an international setting, where dates and
times from different regions might need to be stored in a database,
to set up the server on UTC time just to avoid this problem.
Me, I have to
a. find all the places this will affect in thousands of lines
of code,
b. try to decide what impact going to UTC on the server will
have on things like scheduled tasks, email servers, etc,
c. then figure out whether there is any way to repair tens of
thousands of corrupted records
