For each time change (summer and winter time), certain workflows must be adjusted manually, since the time zones are hard-coded.
Daylight saving time adjustment: +1 → +2
Winter time adjustment: +2 → +1
This creates quite some overhead, a risk of forgetting something and workflows that then no longer function correctly.
When I was in School i always think that why school timing change in Winter and Summer, In Winter School Timing increase than Summer but still I do not get any answer.
