Piwigo uses server's local time to populate date/time fields on API responses.
When the API client is in a different timezone it is impossible to tell how these values should be adjusted in order to display time values accurately (or perform a 2-way synchronization of metadata)

I believe web applications should display date/time values in the W3C format (ISO 8601), which includes the timezone shift from GMT. This way any client application can correctly translate these values into the local time zone.

We certainly have to improve that, but pwg.session.getStatus already gives you the current_datetime. See http://piwigo.org/bugs/view.php?id=2243 and it was on your request if I remember correctly :-)

Your are right! I forgot about that. I can certainly detect the time difference between the client and the server that way.
There is still one more issue which stops me from implementing a metadata sync feature:
