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 lyx-users@lists.lyx.org http://lists.lyx.org/mailman/listinfo/lyx-users
