Java 1.4 and Daylight Saving Time 2007

The current version of Java 1.4.2 for Tiger, 'Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_09-244)' does not handle the new 2007 Daylight Saving Time rules correctly. Will Apple be updating Java 1.4.2 to the version that does support 2007 DST correctly? (at least 1.4.2_11 is required per Sun, http://java.sun.com/developer/technicalArticles/Intl/USDST/).
If so, when? Thanks!

Since you didn't list your computer, here's a link to Java 5.0 release 4 for both PPC and Intel-based Macs, which came out in April: http://search.info.apple.com/?q=J2SE50Release4.dmg&type=kbdload&search=Search&lr =lang_en&search=Go. That should solve your problem.

Oracle WebLogic Server (WLS), Time Zones, and DayLight Saving Time (DST) Changes

Hello,
We are approaching this time of the year again...
I would like to redirect you to the Support Note 1370083.1 "Oracle WebLogic Server (WLS), Time Zones, and DayLight Saving Time (DST) Changes"
This note lists what is to be expected from WebLogic Server regarding this time change period, in terms of behavior, both for the engine and the applications deployed onto WLS.
Regards,
Patrick.

Clock UI control and daylight saving time.

Hi,
We have a customer that has several sites around the world.
In a VC-model I like to use the Clock UI control to display the times of the different sites.
This can be done by setting the time zone in the control properties.
A long ago we have introduced daylight saving time.
It seems that the clock control does not do anything with this ?
How can I change the time zone when the model is running ?
Can it be done by an expression and how ?
There is also a problem of the country, some have DST, others dont.
See http://en.wikipedia.org/wiki/Daylight_saving_time_around_the_world
Example:
I have 2 clocks and the end-user lives in Amsterdam:
Amsterdam, time zone = GMT + 1
Santiago, time zone = GMT 4
During the winter in Amsterdam it is summer in Santiago and has daylight saving so the time in Santiago should be GMT 3 in stead of GMT -4.

With the current version of VC / flash, it is not possible to display the correct time all the year 'round.
If you only want to show the (user) current time then you can use this VC clock object.
If you need to show clocks from different cities around the world, than its better NOT to use the VC clock.
Because you can not define the country and city in the clock properties, that determine the use of DST, it will not always show the correct (default / DST) time.
Solution:
Add a HTLM-view to your model with a links to a web clock.
Nice (free !) clocks can be found (and customized) on <a href="http://www.worldtimeserver.com/clocks/wtsclock001.aspx">worldtimeserver.com</a> or <a href="http://www.timeanddate.com/clocks/free.html">timeanddate.com</a> .
Example:
For the city Santiago (Chile) the URL =

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.

TimerThreads and daylight saving time

I have this task that I need to do everyday at 0:00 AM.
I am using the ScheduleAtFixedRate method to perform this starting it at 0:00 AM and running it again every 24 hours. It is very important to run at 0:00 because it involves money a a reconciliation file.
According to the API documentation:
Fixed-rate execution is appropriate for recurring activities that are sensitive to absolute time, such as ringing a chime every hour on the hour, or running scheduled maintenance every day at a particular time.
My question is what about daylight-saving time ? What happens to such a task that is supposed to run every day at 0:00 ?
Thanks
Luis Cordeiro

My guess, and it is just a guess, is that the task will run every 24 hours, and therefore after a daylight saving time switch you will find it running at 01:00 or at 23:00. But I would suggest you test for yourself. Set up a test program that schedules a task every 3 hours, change your system's date and time to be 5 hours before the end (or start) of DST, and see what happens after it runs for 6 hours.

TimeZone getDisplayName and Daylight Saving Time

Hi all,
Is this a good way to get "CST"/"CDT" accurately?:
// Determine whether or not we're in Daylight Saving Time
// (affects the CST/CDT/etc. printing in the output).
boolean isDst = false;
if (cal.get(Calendar.DST_OFFSET) != 0) {
isDst = true;
Thanks so much :-)

I'd use one of the TimeZone methods, for instance inDaylightTime(date); one of the other DST methods may work better for you.

Problem with SLQ Date and Daylight Saving Time

Hi everybody!
It seems, that when I have a date in the database, which falls on start of the daylight saving period, it is converted to the previous date.
Example: '2001-10-13' will become '2001-10-12' after doing a date = rs.getDate() and then converting back using date.toString().
This caused a lot of trouble because the date value is part of an unique key constraint!
Currently I wrote a wrapper method, which obtains the date as string and converts this one into a date by setting the hours to 12:00.
Does anybody know a straighter way to avoid the conversion?

Because the default time zone is using day light saving time. To remove this feature, reset your default time zone at the very beginning of your program:
TimeZone.setDefault( new SimpleTimeZone( TimeZone.getDefault().getRawOffset(), TimeZone.getDefault().getID() );

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.

Oracle Fix for U.S. Daylight Saving Time Changes in 2007

Hi --
Does any one know that if Oracle 10g Application Server (9.0.4) or Oracle 10g Application Server (10.1.2) as a fix for this issue.
Summary of the Issue: Information about the impact of the US Energy Policy Act of 2005, which changes the effective dates of US Daylight Saving Time (DST) in 2007 for the US. The passage of the Energy Policy Act of 2005 alters the Daylight Saving Time (DST) start and stop dates by four weeks. Extended Daylight Saving Time will begin in March of 2007.
The details for the issue can found at this location:

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.

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.

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.

Hi --
I am having an issue with Oracle 10g Application Server (9.2.0.4 and 10.1.2) and BEA Weblogic (8.1.4) upgrading their corresponding JDK's to resolve the Daylight Saving Time Changes. Right now these app servers are using SUN jdk version, whcih prone to the DST issue, less that JDK 1.4.2.11.

SAP systems and Daylight savings for 2007

Hi,
We are discussing about the Daylight Saving time changes in USA for 2007 and its effect on SAP Systems.
<i>"Beginning in 2007, most of the U.S. will begin Daylight Saving Time at 2:00 a.m. on the second Sunday in March and revert to standard time on the first Sunday in November."</i>
Wondering, if we need to change any variable settings to take into effect? If so, could anyone give details on it.
Wondering if SAP systems time is getting sync with Database servers or O/S ?
Thanks,
Sam

Hi,
The beginning of daylight saving time is normally not a problem as the time will jump from 2:00 to 3:00, so seen from SAP that no problem. You will only have a 1 hour hole, as the system had nothing to do for one hour.
So there are no settings or so to maintain or change. Just let SAP system run...
But it is different when switching back to "normal" time, as there you will have the so called double hour, and even as SAP is working on a solution to this, it is still recommended to shut down the SAP system for this period.
(searching for the term "daylight saving time" in OSS should give you some notes explaining how SAP is handling it)
As i know SAP system is taking the time from OS, but you can se what time the SAP system has, by in the GUI menu to select the "system" => "Status"...
(In the Popup you can se it in upper right corner)
Regards
Rolf
