How do you synchronize with and translate to timezones in Andromeda?

>That's irrelevant

It is proof that your format does not represent instants in time because instants in time can be sorted across timezones.

>Besides, you could, assuming you have a timezone db on the side.

No, because you don't have future versions of the timezone database.
