format_date? which timezone to use?

There's an issue with some of the dates in tokens that they don't get set to the right values.

Of course, the question is what's the "right" value?

I'm writing here to ask if you'd rather get the server time or the default site time or the user's timezone.

The first person who asks for "configurable by the token admin" will get stabbed with a "work on token2.x where attributes are possible"-spoon. (yes, a spoon, it will hurt more).
