Anyone tried using zdate/DSTswitch_contloctime ?

Hi guys!

As the end of daylight saving is approching we were just planning the shutdown of our SAP systems when we found the option to slow down the time of SAP with the parameter: zdate/DSTswitch_contloctime ?

My question is whether anyone tried this before? Does this really work? What happens when the OS changes the time back?

Thanks,

Peter

    By default the parameter zdate/DSTswitch_contloctime is ON

    • Hi Peter,

      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

    Hello,

    As mentioned in note 950114, a functionality was implemented so that

    the time during the daylight saving time switch runs 'slower' which

    could help to prevent a 'necessary downtime'.

    Unfortunately the only component which declares itself to be able

    to run with "zdate/DSTswitch_contloctime = on " in the double hour

    is SAP_BASIS (please see note 7417). The only application component

    known to support this is banking, but also this application still

    recommends the downtime.

    regards,

    John Feely

    The best is not to use daylight saving feature at all, but run in UTC for continous operation.

    Be aware of restrictions regarding time zone settings at user level and connected systems doing data exchange with each other.

    See note 7417
