Switch from daylight saving time to winter time

Hello,
Can somebody describe why it is recommended (note 7417) to shut down the system for a little over two hours? Why is is not enough to deactivate the system 5 minutes before last daylight saving time hour has started and activate it when the winter time is started? Why should we wait until the first hour of winter time has ended?
Note 7417 gives the following example:
'If the hour from 2:00 to 3:00 occurs twice when you change to standard time, you must deactivate the system from 01:55:00 AM until 3:05 AM"
It is not clear, why the system cannot be activated at 2:05 AM after the time is switched...
Thanks in advance,
Yelena

Hi Yelena,
Check the note 102088, it's clearly mentioned about 'double hour' and why it need's to be shout down?.
Regards,
Hari.

Switch to standard time from daylight saving causes error - iOS 7

Hi there,
Today (27-Oct-2013) the time was switched back from daylight saving to standard. When looking my iPhone, I noticed that although the clock correctly displays the current time, the standard weather app still uses the time according to daylight saving (i.e. showing one hour ahead) and what is more interesting, the calendar acts weirdly, showing the correct time, but placing it in the old daylight saving time, i.e. 7:46 AM is shown as a line between 8:00 AM and 9:00 AM! It is really ridiculous and it seems I cannot change these. I restarted my iphone, turned off and on again using carrier provided time, but nothing changed. Any clues?
Using iPhone 5 and iOS 7.0.2.
Any help is appreciated.

Problems with time, time zones have been quite common. Clearly, my brand new, the most forward thinking smartphone has the same bug. Sometimes I wonder why Apple is unable to get basic things work? they simply don't care, that's all.
Issue with the line materializes itself on my iCal on iMac as well
I hope, at least alarm will go off at the right time Monday morning
BTW: last year when I was on trip to Chile, at one night - suddenly - out of the blue - time changed on all our apple devices.. it's bad when you've got your flight next day and don't know when to wake up weeks later I have found out information Apple did not update their list of timezone changing dates.. for couple of years...

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.

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.

Why are addresses dropping off my Comcast webmail address book? I am not using Outlook - Comcast webmail. Comcast said it could be a Mozilla problem. I got a new computer early July & switched from Explore to Mozilla at same time.

Early July I got a new computer & switched from using Internet Explorer to Mozilla Firefox. I just noticed that some names in my Comcast webmail address box have been disappearing. I contact Comcast this morning & they couldn't give me an answer except to say change web browers. I didn't have the problem when I used Internet Explorer.
== This happened ==
A few times a week
== I noticed it some time week of 7/19.

That's the reason I left Comcrap. Never a solution. Never a straight answer. Always blaming some one else.

Plantronics Legend: Switching from headset to phone all the time

Hello,
I have a problem with my Plantronics Legend in connection with iPhone 4S / IOS6:
It only affects calls. I have the headset on and start a call. I will show me that PLT_Legend is active and I hear it ringing in the headset. Then it switches the sound back to the iPhone! I click on the headset again and have the sound there, and after a second, it's on the iPhone again. This goes for up to 10 times until the call stays on the headset. This is serious. I cannot talk in the car, and can make no business calls!
Thanks in advance,
Julian

Thanks for your answers.
@gwforeman: I bought another identical model, and this works fine. So it's the headset.
@Wayne: I already did that, with no success
@epekarik: That's how it went with me, too! No problems for months, then the problem started and got worse over time.
In summary it seems like a hardware problem. The last thing I can think of is resetting the headset to manufacturers setting. Did you try that, epekarik? I dunno how to do, if even possible.
Regards, Julian

How can I switch from photos saved as MPEG4 in a slideshow to individual JPEG photos?

When I imported pictures from my camera, I inadvertantly saved them as a slideshow. In order to be able to burn these to a CD that will play on a DVD player or Windows computer, it seems the pictures need to be saved as individual JPEGs, not MPEG4. How can I change the format, or switch the view?

An mpg4 is a movie, you can't break that apart to individual frames, I'm afriad. However, I do not believe this is correct:
In order to be able to burn these to a CD that will play on a DVD player or Windows computer, it seems the pictures need to be saved as individual JPEGs
To play on a DVD player you need to use an application that can author such a disk. iDVD if you have it, or Toast. Search on MacUpdate

Recurring events off by 60 minutes after daylight saving time switch

I searched but didn't find this exact issue anywhere. Following this past weekend's switch to Daylight Saving Time (DST), iCal recurring events have been shifted one hour later. It is a problem that I encountered with my own web calendaring application, wherein the offset between UTC and a given time zone changes with the coming and going of DST. I am curious why Apple has never instituted a fix for this, especially considering that the fix is so simple. All that must be done is detect whether the original datetime is in DST or not. If it is not, and the given recurrence is, then you must subtract 60 minutes from the recurrence's datetime. Similarly, if the originating datetime is in DST, and the given recurrence is not, then you must add 60 minutes to the recurrence's datetime.

I have the same problem but much worse. Only 5 of my 18 recurring weekly events have shifted, so I didn't realize that anything was off until I missed one of my classes today. This seems weird....

Summer Time -- Winter Time

Hello fellow admins,
In Europe, during the night of october 29th to october 30th, we will change from Summer time to Winter Time.
In my company we have always stopped our SAP systems during the "time leap" from 3am to 2am.
We know that, when setting the system parameter zdate/DSTswitch_contloctime = on, the SAP abap kernel will be able to "slow" time to avoid the time leap.
We are now investigating if we could avoid to stop our ECC6, R/3 4.7, SRM and CRM systems.
What bothers us is that SAP only guarantees the BASIS module and tell that we should check each functional module to decide if a time difference between SAP time and legal time up to 30 minutes is acceptable for our business processes.
I would like to do a kind of poll to know what you do with your own SAP systems.
Could you, please, answer by telling which SAP system is used and if you stop it or keep it running during the time change ?
Thank you in advance for sharing information.
Regards,
Olivier

Hello
During that period our business will send a notice to the end users that the system will not available during this period and we stop all our applications(DEV, QAS & PRD) ECC, ECC HCM, EP, SRM, Solman.
It's always good to bring down the system to avoid any business impact or any new challenges.
Thanks & regards

Switching from a 4g to 3g phone and then back ..weekly.. sim card?

If this has been asked already I apologize...I've seen different answers and I just want to get it straight.
If I have a 4g phone ( sim card) and want to go back to a 3g phone (I'd like to do this several times a week). How can I do this without requiring a new sim card? Before, between 3g phones, all I had to do was call *228 and that was that...can anyone explain the easy way to do this?

So I got a Samsung s4 when it was free upgrade and then I switched back to my basic cell phone so I could give the S4 away., I've done this switching from smartphone to basic phone multiple times in the past and each time they removed the data plan after I switched back to a basic phone.
This is exactly why they changed the policy. They were losing money on the smartphone you would by, but then only pay access charge for voice and no data. The data profit was built into their business model to pay for the higher price of the smartphone.

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.

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 !

How do i get calendar syncing recurring events from outlook to iphone to handle daylight saving time

When I sync recurring events of my PC Outlook on to the iPhone calendar they appear one hour later during summer i.e. between Mar 26th and October 27. I have a weekly thing every wednesday at 8pm that appears at 9pm in summer - so outlook seems to be sending the info in UTC time but the IPhone isn't compensating for summer time.

What do you mean "correctly". If I enter a recurring (weekly) event in Outlook at say 8pm every Monday from February till December, then Outlook calendar propagates it at 8pm every Monday from February till December, and I can see it on each Monday regardless of whether it's standard time or summer time. However when I sync with the iPhone calendar through iTunes it transmits just the start date/time and end date, and the iPhone then recreates the series of events (provable because it creates occurences that I have deleted on Outlook). However it propagates the UTC time at the start date, and gets confused by the change to Summer Time in March (and Ocotber). The iphone "corrects" the (UTC) time for Summer Time so it starts at 8pm, all summer the event appears at 7pm, and goes back to 8 in November. I have tested across both boundaries - if a recurrence starts in summer time at 8pm then from November it gets an hour later, 9pm. And you can't solve it by turning off Local Time handling on the iPhone because then all individual events through the summer are an hour out. This is a bug.
Workaround - enter separate recurrent events for each time period, so in a calendar year 3 events: Jan-end March, April-end October, Nov-Dec

Date Time in Coldfusion at Daylight Saving

Hi
In coldfusion, I have problem creating Date Time using CreateDateTime when the daylight saving switch. For example
CreateDateTime(2011,3,13,2,0,0) gives error.
Also if you do like this
DateAdd('h',1,CreateDateTime(2011,3,13,1,0,0)) gives "2011,3,13,3,0,0" ie instead of 2AM it returns 3AM. This is happening every daylight saving switch time.
This is a bug in coldfusion?
It should be fixed by Coldfusion.
Thanks

This will show wrong hours (2 is missing)
and that means you've fallen into timezone hell.

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 =
