Summary :
The SAP profile parameter zdate/DSTswitch_contloctime ensures continuous system time handling during Daylight Saving Time (DST) transitions, avoiding backward time jumps that occur when switching from summer to winter time. As described in SAP Note 7417, new kernel technology smooths time flows in the "doubled hour", curbing the abrupt one-hour shifts. This parameter can be dynamically adjusted via transaction RZ11, with choices to either align closely with official time or prevent time leaps, risking up to a 30-minute deviation from the official time. Compatibility starts from Kernel 6.40 Patch Level 131 and is available in subsequent versions.
