System time did not update after the daylight saving change
The computer clock did not reflect the daylight saving time change. The technician verified the time zone and daylight saving setting were correct, then forced a time sync so the displayed time updated.
Killed once by someone from XL.net, on 2025-11-11.
What you see
- System time did not reflect the daylight saving time change.
- Time zone and daylight saving settings were already correct, but the displayed clock was still wrong.
Why it happens
Suspected The clock had not refreshed automatically after the DST change; the exact reason was not established.
When it shows up
A Windows computer shows the wrong clock after a DST change even though the time zone and daylight saving setting are already correct.
You are in this case if:
- Date and time settings show the expected time zone.
- Automatic daylight saving is enabled or otherwise already set correctly.
- The displayed time is still wrong until time synchronization is run.
