The TZ project, which maintains the timezone database, would be a good place to
find pointers. They don't actually manage that information, but pointers to
"shape files" that translate map coordinates into the timezone identifier are
available.

For a slightly higher-quality conversion, the attribution entries in
the map file should have a third field: timezone. IANA zones are
acceptable.
This wouldn't change how commit times are stored internally, but the
Git tools use it for display in local time.
