Daylight Saving Setting in SAP

To convert the system time to local time of the plant and if the local time of the plant observes day light then result is 1 hour off sometimes. This problem occurs due to time difference of daylight saving. If you are facing this problem (like me) then please check your DST system using transaction STZBC.
