Daylight Savings Time (DST) fix in firmware

Yet another DST time has come and gone (well, not really, in that the router WRT54G thinks that time changed last weekend when it doesn't actually change until THIS weekend) with no firmware update for the new (well, not really, it's old now) legislation.

You will find that Linksys equipment is ok. But remember it's not professional equipment. You get what you pay for and the support proves it.

Daylight Savings Time (DST)

Hi,
Can any body tell me what is Daylight Savings Time (DST)? What is its significance in Java?
Nischal

nrlz is of course pulling your leg (sorry to ruin your fun nrlz). DST is the system wherein clocks are set forward an hour in the spring and back an hour in the fall. It's significant in Java if you need to model it in your Java application.

Daylight Savings Time (DST) - Sun JVM Upgrade Question

I am using JRun 4 Build 106363 on a MS Windows 2000 Server.
We have updated our Windows 2000 server for the new DST. I also
updated Sun j2sdk1.4.1_02 using Sun Java SE TZUpdater Tool.
Do I have to upgrade to Sun's JVM version 1.4.2_11 (see link
to technote below) or will the steps I've already taken ensure
correct DST date/time handling?

You need to upgrade to 1.4.2_11.

Australia 2008 Daylight Savings Time DST Changes

Lasy year some Australian states changed the Date that DST is ended, from 30th March to the 6th of April:
See for details: http://www.lawlink.nsw.gov.au/lawlink/cru/ll_cru.nsf/pages/cru_daylightsaving
I can find patches for the 2006 change made to accomodate the commonwealth games, but can not find patches for the changes that come in to effect 2007-2008.
Anyone know where these can be found (I assume they exist).
Thanks in advance,
John

The JDK download page has a timezone updater that you can download. Each new Java version contains updates to the tz rules, your version may already include what you want.

Daylight Savings Time 2007 - firmware upgrade ?

In 2007 the start and end dates are going to be different for Daylight Savings Time. As a result, servers are going to need to be patched. Here is a related link I came across:
http://sunsolve.sun.com/search/document.do?assetkey=1-26-102617-1
My question is, how do I know whether or not my firmware (PROM) needs to be updated too ? I have searched and have not found a lot of information on the topic of the firmware. Does anyone have any good links or pertinent information on whether the firmware would need to be updated or not ? I have several Netra T1's, Sunfire V480's, and my Sunblade 100 workstation that I am concerned about. Here is the OBP level from one of my V480's that is on Solaris 8: OBP 4.6.8 2002/09/04
and here is the OBP from a V480 on Solaris 9: OBP 4.10.14 2003/11/19.
Thanks for any information.

The platforms mentioned in the Sun Alert 102617 that you linked above,
are all Sun Fire Midrange Server systems.
Their "firmware" is a part of a completely different sort of of architecture.
Their system controllers are a tiny computer, with its own OS, inside the Sun Fire system.
That Real Time Operating System (RTOS) that runs on the SC's has its own
time-of-day function that is independant of whatever Solaris gets installed
to whichever domain or domains you configure to the computer.
Thus the need for the Sun Alert, separate from any TOD discussion for Solaris..

HOw do I fix the fact that ical jumped (almost) all my events post daylight savings time change an hour ahead?

A few weeks ago I noticed that everything past 3/8 was an hour ahead, and I assumed once daylight savings time changed it would all jump back. It hasn't, and I don't know how to continue scheduling events or if I should change them all. I read that (a few years ago) the suggestion was give it 24 hours to adjust??

I think this problem is more complex. Background - UK clocks went back at the end of October; the USA went back one week later. I am in the UK and my Outlook calendar contains appointments created in the USA.
Someone in the USA created a recurring appointment before any clocks went back. In Outlook everything is correct. The meeting times are the same each week except for the one week between the two clock changes when, quite correctly, the meeting shows up one hour earlier. When I sync with my iPhone, the meeting shows at the same time every week regardless - this is incorrect.
Someone in the USA created a recurring appointment in the week after the UK clocks went back but before the USA clocks did. Outlook correctly shows the first occurrence as one hour earlier than all the following occurrences. Unfortunately - and this is the really nasty bit - the iPhone shows ALL the appointments one hour earlier than they should be. The only one that is correct is the first one.
This is a nasty bug and something that Apple needs to fix.

10.3.9 Daylight Savings Time Problem (DST Patch applied), it was working

We have about 30 Macs running 10.3.9, all of which were patched last year with the DST patch (2007). They are all configured to set the date and time automatically using time.apple.com. The user account used by the people using them is a non-administrator account.
Since Daylight Savings Time changed in March 9, 2008, they correctly changed their time until late last week (end of March), when several of them went back to the old time. If I open the Date & Time System Preference Pane and authenticate, the clock changes to the correct time, without any further input from me other than authenticating as the admin. Once changed, some but not all go back to the incorrect time about a day later.
Any ideas? I am trying to see if there is a simpler solution that resetting PRAM, throwing away cache files, etc.
Other machines running newer versions of the OS don't have the issue.
Thanks in advance for any input and/or advice.

DST-2007 Daylight Savings Time Patches for MAC OS

I have found Daylight Savings Time patches for other platforms.
Is there a patch for Daylight Saving Time for MAC OS?
Thanks.

They are the settings I have always used and my computers have always reverted to and from Daylight savings (except of course I'm in Queensland, Then I have to reset my location and remember to set it back.
Other than that if may come down to trashing your pref file for date and time.
Good Luck

How to fix daylight savings time switch

Times jumped ahead several weeks ago for daylight savings time, and I dont know whether to change them all manually or not.

thanks for responding ; I just changed all my entries after Sunday manually just now. I'd waited over 36 hours and it hadn't adjusted. Sure hope this doesn't happen everytime there's a time change -- I don;t remember it happening before.

Daylight Savings Time Change Mar-2007

Is this years new date for DayLight Savings Time going to affect my WRT54G v3.1 router? My firmware is 4.30.5.
Also, does anyone know why the opening admin page for my router say I have a WRT54GL?

Versions 1 - 4 and GL's use the same firmware because they all have the Linux operating system.
The new release firmware for versions 1 to 4 is 4.21.1 If there is no fix for the new DST in 4.30.x it might be in the new release.

Multiple instances spawned after daylight savings time change

This is a known issue and there is an SAP Knowledge Base Article created on this issue:
1448881 - Multiple instances spawned after daylight savings time change
Below is the information from the SAP Knowledge Base Article:
Symptom
Scheduled reports that are supposed to run once a day, run multiple times.
Duplicate instances are being created.
Environment
BusinessObjects Enterprise XIR2 SP5
BusinessObjects Enterprise XIR2 SP5 + FP5.x
Reproducing the Issue
A report is scheduled to be run on a daily basis - this is a Recurring schedule.
Normally the report runs once a day, at a particular time.
After Daylight Savings Time change, the report runs at the specified time, but immediately after the successful instance, another instance is spawned.
Many more instances spawn after each instance completes.
Cause
This is a known issue: ADAPT01318487. This issue is because of DST and how our code handles this change.
Resolution
There is currently no known fix for this issue. There is however a script that can quickly resolve the problem.
The issue it seems is related to Daily recurring schedules.
What this script will do:
it will run a query to display all your DAILY Recurring jobs
you will have the option to choose your jobs and reschedule them by 1 hour
you will then highlight the same job and change them back by 1 hour
by modifying the schedule times, you are modifying the schedule itself and this will keep the issue of duplicate instances from occurring.
Exact Steps to Complete:
Stop the Job Servers.
Double click on the .hta file.
Change the System Name to that of your CMS name.
Add the Administrator's password.
Click Logon.
Click List All Recurring Instances.
Select All.
Make note of what it says in: Schedule Selected Recurring Instances: Should be 1 hr earlier.
Click Reschedule Selected Recurring Instances.
Choose All instances again and change Schedule Selected Recurring Instances to 1 hour Later.
Click Reschedule Selected Recurring Instances.
Now start your Job Servers.
The issue should not occur again.
The Script is attached here, but please review the SAP Knowledge Base article 1448881 as well

Hi Nicola,
- The multiple spawned instances issue ONLY affects XI3 SP3+ only. For XI3 SP1 and SP2 all Fix Pack levels this is not an issue as it was introduced as a problem in SP3.
- 1568239 notes the Java version and can apply to all O/S environments and is updated to reflect that.
If you are located in Europe you can also apply the patches in advance of the DST change to avoid the problem. If you are in Americas at this point utilizing the clean up scripts for this year is the approach needed to clean up the spawned instances and reschedule the existing schedules.
Thanks,
Chris

Daylight Savings Time and Alarmsk

Since the daylight savings time updated over the weekend the alarms I had programmed on my iPhone will not set properly. The phone displays the correct current time so I know the clock has updated but any alarms I have set for the hour of 2am - 3am don't display the proper time. They keep reverting to 1-2am. I have deleted them and recreated them with the same results, on 2 different iPhones, a 4gig and an 8gig.

I see im not the only one that gets up early. v1.1.3 and updated to 1.1.4 I am unable to set the alarm to any time in 2AM (2:01, 3, 4, 5, etc..) any time set to 2AM shows 1AM in the alarm. 2PM shows fine. Any hour of the day shows fine. The error is setting a time of 2AM as it will not show that time and will revert to 1AM.
I am in a zone that uses DST.
I guess apple doesnt want us to wake up to pay the bills.
I hope someone has a fix for this before I goto bed... busting out the old alarm clock now.

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)

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.

JRE Update regarding Daylight Savings Time changes

Hi,
Is there a JRE Update to be released anytime soon dealing with the US Daylight Savings Time changes?
A similar update was released for the DST changes in Australia (JRE 1.5.0 Update 6). The link to information page is:
http://java.sun.com/developer/technicalArticles/Intl/AusTimeZone/
If there is an update coming for US, when would it be?
Thanks,
Vinay.

If you had read through the bugs related to the one
whose link was in the post just before yours, you
would have seen this one:
http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=639
1777
which appears to answer your question.If I read the bug report right, a fix was made to JDK 1.3.1 to handle the Australia situation. Are you pointing me to the workaround or a potential fix for the US timezone issue?
The bug report says: "This fix is based on tzdata2006a." Does this tzdata file include an entry for the March 2007 onwards change in the US?
