Which sync you’re referring to? I’ve read the code for change tracking in LyX and IMO its as follows: 1. LyX saves the timestamp to the document file as Unix timestamp. No timezone involved. (*) 2. LyX converts this timestamp to string presentation via gmtime(3) and asctime(3). No timezone involved again. IMO there is no sync problem in LyX documents. The saved timestamp is always w/o timezone. The timestamps in LaTeX export file should be interpreted as UTC. (*) Others problems are implied: 1. Unix time_t doesn’t consider leap seconds. 2. On 32-bit systems the time ends on January 19, 2038. Stephan -- lyx-users mailing list [email protected] http://lists.lyx.org/mailman/listinfo/lyx-users

Thanks for checking. Insert date gives the correct (Dutch) time here, too. But
the time stamps added to the LaTeX preview are always exactly two hours behind.
A riddle.

For me it also works correctly. I am in the same timezone (Amsterdam), and my
LyX date format is %c
(Tools / Preferences / Output / General / Dateformat).
Insert / Date gives Sun Jun 18 20:24:41 2023

Of course, sorry about that. This is on LyX 2.3.7, macOS 13.4, on an M1 iMac. I
am in the Amsterdam timezone, and time stamps like \lyxadded{RH}{Sun Jun 18
13:00:02 2023} are two hours behind. I worry about this a little bit: time
discrepancies can cause nasty synchronisation issues sometimes. This has not
happened so far, but since I am working on two machines, I have to be careful.
