This is not really an ABAP related question....Search on the internet and you will find out. It has to do with shifting hours between summer and winter for saving (Daylight SAVING) 'money', energy etc.

Main significance in SAP? You will have to take this into account whenever you are timestamps in your coding for example. In SAP timestamps are stored in UTC (Universal Time).

Example:

In your transaction your are saving an appointment on 11.06.2009 00:00:00, depending on your timezone (CET in this example) it will be stored as 20.090.610.220.000 (UTC). So, the date is NOT on the 11th (CET), but on the 10th (UTC)!!

There are some standard function modules you can use: IB_CONVERT_INTO_TIMESTAMP

and IB_CONVERT_FROM_TIMESTAMP.

Look at internet information source like [wikipedia|http://en.wikipedia.org/wiki/Daylight_saving_time] for this kind of question (actually not an Abap subject ?)

Have you a more precise question, you may also look for OSS notes on "daylight saving time" keywords.

A brief description would be helpful

Thanks,

Like I already mentioned in my first reply, use the function modules for conversion.

Also look at statement [CONVERT TIME STAMP documentation|http://help.sap.com/abapdocu/en/ABAPCONVERT_TIME-STAMP.htm] for addition DAYLIGHT SAVING TIME dst.

LOL may be they are not aware of the detectives in SDN forums. Time to say goodbye to both of them soon.

Since we are talking of two different timezones, it obviously took that much time to CONVERT THE TIMESTAMPS.

After the point-gaming comes the points-distribution!!!

Could be that the OP is bribing you with points so that you wont report to the moderators

Yep, it's points-wasting time now...

> You can see newer things by the hour ...

Yes, it takes approximately one hour for the caches to clear as well.

Sorry, the guest-o-blaster has been in for recalibrating. We will warm it up for you.

Now that is another original one, which we have not seen before.

Can you ask Vijay Vorsu whether it is okay to delete his ID as well? He should be sitting right next to you.

Perhaps the two of you should consider taking out re-insurance from your client against this risk, next time...

Bye-bye,
