7.0.12rc1, 7.2.6rc1, 7.4.0beta2
Steps to reproduce:
- Open any page with graph and time filter, for example Latest data -> Item - Graph
- Type "now-Xd/d" in the "From" and "To" fields.
Where X is the number of days since the "Daily saving time" was and minus one more day.
For example: today is 08.04.2025 (timezone Europe/Riga). DST was 30.03.2025. So wee need to subtract 9 days to 30.03.2025 and -1 one more day. As result type "now-10d/d" and graph is
From =>2025-03-29 12:00:00 , To => 2025-03-29 11:59:59
- Apply filter
- Click "zoom out" in filter or double click on graph with mouse
Result:
Zoom out shifts "From" and "To" by 24 hours, but due to 1 hour daylight saving time change, the filter result will be From =>2025-03-28 12:00:00 , To => 2025-03-30 12:59:59
Also if select time when the clock change occurred (March 30 from 3:00 to 4:00), for example now-8d-31h and now-8d-30h , you can see that the time on the graph axis does not change
-32h
-31h (old time 3 AM, after DST 4 AM)
-30h
Expected:
the result in filter are From =>2025-03-28 12:00:00 , To => 2025-03-30 11:59:59
