I live in a region with different time settings for summer and winter (summertime/wintertime). How does PRTG handle data when daylight saving time is set/unset?
How does PRTG handle daylight saving time (summer time, winter time) settings?

PRTG and Daylight Saving Time
When using daylight saving time, you should set the according flag so Windows changes time automatically. So this is done automatically and you don't have to care about it.
Internally, PRTG always uses UTC. When viewing data it will be recalculated to match your current time zone. In data display you will see a "gap" respectively double values for one hour when changing between summer and winter time. This affects display only, not the real data.
