Summer Time --> Winter Time

[Former Member]

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

Hi Olivier,

Was wondering how you went with your DST shift into winter time (eg double hour).

Did you stop your SAP systems?

If not, and you left them running, how did everything go?

Cheers

Hi,

In the weekend of October 29 and 30 2011, Europe will switch from Summertime (Daylight saving time) to Wintertime. This means that on Sunday October 30 at 3.00 CET (GMT2), the clock will be set backwards to 2.00 CET (GMT1).

As a consequences all SAP servers (ECC6 and SAP Netwever) will be shutdown on Sunday October 30 2011 between 0.30 CET and 2.30 CET.

Sanjeev Kumar
