Description Jonas Lund 2019-03-31 20:46:18 UTC
Description:
With an open document overnight, if a daylight savings time changeover has happened while the document was open, trying to re-save the program gives a warning that another application might have changed the document even if that isn't the case.

Marking as minor instead of trivial as this touches upon file saving correctness so a fix should be vetted. (possibly leaving as-is might be safer overall)

Steps to Reproduce:
1. Open any document, possibly save also
2. Set the system clock to just before a daylight savings time changeover
3. Wait for the DST changeover
4. Save normally

Actual Results:
The program warns that the file might have been changed by another program.

Expected Results:
The program should save without an issue.


Reproducible: Always


User Profile Reset: No



Additional Info:
The program probably uses a stat function or similar that uses local time to see when the file was saved, whereas it probably should have used a unix timestamp or similar to determine this.

Hello Jonas,
Thank you for reporting the bug.
it seems you're using an old version of LibreOffice.
Could you please try to reproduce it with the latest version of LibreOffice
from https://www.libreoffice.org/download/libreoffice-fresh/ ?
I have set the bug's status to 'NEEDINFO'. Please change it back to
'UNCONFIRMED' if the bug is still present in the latest version.
