Daylight Saving (DST)(Summer) Time setting.

Hello. I am having two problems:
1...When I turn my computer on, I sometimes notice the time is incorrect and have to re-set it. I'm thinking this could be due to the backup battery (it hasnt been changed in 6 years), so will look into doing that.
2...When I do re-set the time, it is one hour out, ie: when it should be 9:20, it reads 8:20. I can physically re-set it to make it correct, but is there a setting in Preferences that will automatically re-set the time to DST?
Thank you.

If you're looking for an inexpensive upgrade beyond 10.2.8, why not look for a retail black-label Tiger 10.4 install disc? (Make sure any OS X disc purchased from Bay or the like is a retail disc, one with a black label. Model-specific gray-label iscs are just that, model specific, and won't work woth your eMac). Tiger shouldn't cost much more than Panther 10.3 nowadays, and will offer a longer supported life. Assuming you have 6 GB or more free on the eMac HD, and 512MB RAM or more, upgrading to Tiger 10.4 should be pretty straightforward. That upgrade didn't affect any of the programs on my eMac.

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 =

TS1638 When syncing calendar on iPhone with Microsoft Office whole day appointments get moved to double day. I am aware this may be caused by conflicts in clock, viz daylight saving time. However, Outlook seems OK and takes time from Windows time and zone

When syncing my iPhone to Microsoft Outloook all the full day appointments become two day - 2300hrs to 2300hrs next day. Sometimes this will include a nuber of a single day of 23 hours. Looked at solutions and all point to a clock issue or a daylight saving and winter times. Outlook operating time is directly from the Windows clock that incudes the change of times for daylight saving etc. It is set for UTC Dublin, Edinburgh, Lisban, London with daylight saving included in the options. I can't see what I can do.

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!

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.

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

6234 Change to/from daylight saving time or summer...

We have just changed back to winter time, and I am sure that there is a way to make the phone change, without setting the time. I can only find time zones, and have set it to GMT (which is my local zone), but even so, I am sure that there is another menu item somewhere to change to and from summer time. The phone time did not change, so it was already on the right time zone.
I've looked in the user guide, but there is no mention of it.
I can't remember what I did 6 months ago.

hi Peter,
same problem-just gone to winter time (UK)and my 6500s was also set to auto but never changed i evan left it an extra day thinking that i too may have missed a setting or something simelar but had to change it manually today after finally giving up.Thing is this will really bug me til i can solve it.

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.

Brazil Daylight Saving Time Problem

In Brazil, we enter the summer time and my blackberry 9800 torch automatically work, but when I synchronized with the playbook, some problems arose.
The time in the menu setting is correct, as you can see in this image:
But the wrong time remains the main screen:
Does anyone have the same problem and knows how to fix it?
tks,

It did not work.
It is indifferent to select manual or automatic, the problem persists.
I'm in Brazil and with the correct time zone, but we are on daylight saving time.
On the menu setting time and date, the time is right, however, in early 1 hour on application clock and and late 1 hour on the main screen.

IPhone upgrade to 3.1.2. resets date time - no daylight saving

I upgraded my iPhone 3GS to the new OS: 3.1.2 recently. I noticed the date & time were reset to some time way in the past so I reset them to the current date & time. I notice now there's no way in the Settings | General |Date & Time to automatically have the date & time synced with your PC and the iPhone doesn't take allowance of daylight saving time - I added London as a city for keeping track of my time and the Clock shows it as 10 hours behind Sydney time rather than 11, which would be the case if Sydney was set at daylight saving time.
Does anyone have any suggestions as to how I can get my iPhone to recognise daylight saving time again? I can't see anywhere on the iPhone or iTunes to do it, I've tried resetting my iPhone. Nothing is working.

I don't see a DST option either. I assume that Set Date & Time automatically did set from the phone network and that would include DST corrections. Mine is correct now and we are on DST here. Manual says:
"Set whether iPhone updates the date and time automatically: Choose General > Date & Time and turn Set Automatically on or off.
If iPhone is set to update the time automatically, it gets the correct time over the cellular network, and updates it for the time zone you’re in.
Some carriers don’t support network time in all locations. If you’re traveling, iPhone may not be able to automatically set the local time."

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

Conversion from summer time (daylight savings) to winter time.

Hi All,
When converting from summer to winter time (with one double hour) for the ABAP stacks action needs to be taken to make sure no problems arise. For the ABAP stacks there are several possibilities; e.g. see /people/tikkana.akurati/blog/2009/12/09/daylight-saving-time-and-slowing-down-the-time
What about the JAVA stacks however? Is it OK to keep them running.>Or does action need to be taken for JAVA systems to? And what if there is JAVA <-> ABAP communication and the ABAP stack is set to slow time during this hour?
Can anyone advise on this?
Thanks.
Regards,
Bart Groot

Hi,
Well it is no more necessary to stop an ABAP system when coming back to winter time.
Check OSS note 950114 about system parameter zdate/DSTswitch_contloctime
For the JAVA stack, as there is no functional data in the database, I don't think there is anything to do.
You might get strange logs files but who cares ? Java logs files are already so strange !

Olivier

UC560 Daylight Saving Time

Hello,
We have a UC560. Once Daylight Saving Time (DST) was initiated we updated the time in CCA to the correct time - one hour ahead.
The problem: The messages being sent to our PC's when a caller leaves a voice message is 1 hour ahead of the actual time.
Please let us know if you may have a solution for this problem.
Thank you,
Dawn

Okay, I ran the update... Two problems here.
1. Now my calendar events between March 11 and March 31st 2007 are off by an hour (although they show the correct time when you open the event to view it).
It doesn't work to delete the event and create a new one... It still shows as the wrong time. the only way I found to fix the time problem is to set each event for the incorrect time zone (I'm in Pacific and have to set it to Arizona).
2. Each "all day event" I scheduled into my calendar show up the day before the actual event date, yet when I open the event they show the correct date. Example - If I scheduled an all day event for April 19th, it appears on my calendar on April 18th. Yet, when I open the event to view the details, it does say "April 19".
The only way I've found to fix the birthday events to the correct day is to delete each one and re-schedule.
I find this highly inconvenient and and huge time waster. My business depends on my calendar being accurrate and I don't have time to adjust hundreds of entries.
If other folks are having this issue, speak up. It would be great if other folks knew they should wait to install this until a fix is issued.
If it's just me... Well, I guess that *****.
What now?

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.
E

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.
