AIX 6/7 U.S. Daylight Savings Time bug

I saw announcements this past Friday and yesterday about daylight savings time bug on IBM AIX and thought this news might be important to pass around, as the time changes in the U.S. this coming weekend, and the fix requires a system reboot.
Possible Action Required: System time may not change properly at DST start/end dates on AIX 7.1 and AIX 6.1

> Apparently, this is far more complicated than either of us might think. I've heard that from several people.
I don't want to simply sound argumentative (I'm NOT attacking you in any way here), but without some sort of specific evidence of why this would be a complicated issue to fix, I have difficulty believing this. It's easy to say "it's more complicated than you would think," but where is the evidence of this? Where is the statement from Adobe saying that they know about this issue? Where are the examples from the people you refer to that explain why Lr can't do with dozens of other apps -- many of them FREE -- can do without this problem? Are we really supposed to believe that displaying the date/time correctly is so complicated that it's going to take Adobe over a YEAR to fix it?
We're talking about displaying some text from a standard tag. When it comes to this sort of application, it doesn't get much simpler than this. Lr doesn't have to "calculate" anything -- it just has to display the data in this field. How is this any different than displaying the data from any other field. Why is Lr applying an "adjustment" to a field that doesn't need it? Exactly what is the theory behind this being difficult?
Thanks for your feedback,

IdM Scheduler and Time Change to Daylight Savings Time GMT to BST

This isn't really a 'question' , but just a topic for discussion.
We're not live yet, but will be by the time the clocks go back. So I'm just interest to hear everyone's experiences and any issues with regards to the switching to / from DST
I did some "interesting" (or not) tests last night to see what happens with Pending Values which are due to take effect at the time change threshold of 01:00 GMT when switching to Daylight Savings Time (BST) GMT +0100.
It seems as if the IdM scheduler keeps going according to UTC or GMT. However any values provisioned to target systems or to local tables using the ddm.datetime8601 system variable are in local time according to the runtime server or SQL server's locale settings.
I set up a task to output from a javascript the current system date
using the following in the functions.
currentTime = new Date();
return currentTime.toString(); // returns Locale Time String
currentTime = new Date();
return currentTime.toUTCString(); // returns UTC Time String
in the same pass I also output the ddm.datetime8601 system parameter and the ddm.time24 system parameter.
This task was to update a comment on an entry and Scheduled to run at 00:00:00 and was executed at 00:00:06 GMT all times were still in GMT as expected.
Local Time: Sun Mar 27 00:00:06 GMT-0000 (GMT) 2011, UTC Time: Sun, 27 Mar 2011 00:00:06 GMT, ddm.datetime8601: 2011-03-27T00:00:06, ddm.time24: 00:00:06
This task was scheduled at 01:00:00 in IdM and was exectued at 01:00:08 GMT by the runtime, and you can see the local time is being correctly reported as 02:00:08 BST. Note also the ddmdatetime8061 is also 02:00:08 i.e. BST.
Local Time: Sun Mar 27 02:00:08 GMT+0100 (BST) 2011, UTC Time: Sun, 27 Mar 2011 01:00:08 GMT, ddm.datetime8601: 2011-03-27T02:00:08, ddm.time24: 02:00:08
In the database the entry values MXI_VALUES ModifyTime field has the GMT / UTC timestamp.
I also set up some pending value objects to be applied at 00:59:59 and 01:30:00 to see if the 01:30:00 would be 'skipped' as the locl clock change would've gone from 00:59:59 to 02:00:00. Well the pending values were correctly applied and expired and no 'lost' transactions happened as a result of the change.
So essentially it seems to me that the IdM runtime and scheduler times are all based on UTC / GMT.
I guess it's only an issue twice a year if you're expecting something to happen at a specific local time 01:00:00 or if you've got a global user base and their account expiry should be in each user's own country's local time. In these cases, it would seem that you'd need to convert the schedule times and pending value times to UTC first before setting them in the database.
Has anyone else had any issues, thoughts, questions or suggestioins on scheduling tasks which span the DST time change when switching to and from Daylight Savings Time.

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

Outlook 2011 for mac daylight savings time issue

Hello,
I have a problem in my company where after daylight savings time meetings are shown an hour off in the calendar, but in the body of the meeting the time seems fine. The real problem is when after updating the meeting from it's body (just pressing save and
close) the meeting is bloated by an hour.
E.g. if a meeting after daylight savings time is from 11:00 to 12:00, it's shown on the calendar from 12:00 to 13:00, but after updating the meeting it's shown from 11:00-13:00.
This happens only on the macs in the company.
Thank you.

Solaris 10 u8 system did not update daylight savings time

I am running Solaris 10 u8 x86, and my system did not update for the daylight savings time change on Nov. 1, 2009. I am in the US/Mountain time zone. What should I do?
Patch 141517-04 is installed, I assume it came with u8.
Does this have something to with JAVA Time Zone updater? I saw this:
http://java.sun.com/javase/timezones/tzdata_versions.html
Shouldn't u8 take care of all this automatically? Do I have to somehow get TZUT 1.3.20? By contacting support? What?
Any suggestions would be greatly appreciated.

BTW, I'm running 64-bit Solaris as a VirtualBox (3.0.10) guest VM on a 32-bit WinXP host.

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.

Daylight Savings Time and Time Zone Issue:

Howdy! Many of us woke up this morning to be dismayed to find that our iPhone was TWO hours behind instead of falling back one for the Daylight Savings Time adjustment, and were late for church. I have an iPhone 4S, with iOS 5...
I was working at that time of morning, and the initial switch went well. However, when I woke up, the clock was yet another hour behind. A little investigation showed that the Time zone had been changed to Denver (It was previously on Chicaco, and I live in Dallas.) I tried to select it to change it, and it wouldn't allow me. If I turned off the Set Automatically feature, then I could change it, but when I turned the Set Automatically feature back on, it would re-set the time zone to Denver.
I found another thread where they discuss this:
https://discussions.apple.com/message/16644669
To fix this, put in airplane mode, then back out again, then re-choose your correct time zone. If this doesn't work, then try turning your phone completely off and then on again. Thanks to 4n6doc for the tip!
The airplane mode trick worked for me: I turned airplane mode on, then off, then went to the Date & Time and set my time zone to Dallas, TX while the Set Automatically was off. When I turned the Set Automatically back on, it changed Dallas to Chicago, which is what every iPhone iOS I've ever had has done.

Hi,
Yes this is a correct way to fix the issue. One thing however, how did you set the timezone? For correct daylight saving handling, you'll have to use the long version, like America/New Yorw, NOT GMT-5 (for example).

Daylight Savings Time for the USA

I am trying to add a new entry for the new daylight savings time change implemented in the United States in a 4.6C system. I am trying to make the change per SAP note 919538.
The problem is when I go into transaction STZBC, and try to add a new entry for the USA, after I input what was stated in the SAP note and try to save the new entry, I receive an error "Choose the key from the allowed name space".
How have others implemented this change? I am unsure of modifying the entry that is there already for the USA since the sap note says to add a new entry.
Regards,
Doug Slupski

Hi Doug
Isn't this message informational only?? It does not show as an Error. If you hit Enter a couple of times, it should go thru...
I am not sure if it will wipe out the previous entry under the Key "USA"from the table.
Make a note of the previous values before u hit enter. After you have made the change, check if it overwrote that value.
If not, then you should be fine..If yes, chnage the value under USA to he original values and open up an OSS message.
Hope that helps..
Thanks

2007 Daylight Savings Time Changes

What, if any, effects will the 2007 changes to US daylight savings time have on the operation of the LabVIEW 7 Express development environment and deployed applications created with it?

I believe the answer depends on the OS the application runs under.
If MS has there act together and the machine in question has recieved updates, there should be no issue.
If you are running Unix (or a variation o such), a patch must be applied (at least that was the story my wife gave for working all night Saturday night).
I can not answer this Q for Mac or LV-RT running under Pharlap.

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.

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)

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.
