Very cool, if true

That only makes sense because I *vaguely* remember from looking at LJ XML exports that LJ has *two* datetime fields on a post.

AFAICT one was the real, actual time the entry was created, and the other is what is displayed.

Is this to do with displaying the latter?

(I can tell you write UIs for Windows ;) Or that maybe you don't write UIs at all? Labels should be full sentences, not magically completed by the thing you select, for instance.)

> In order to work out what "now" is for you it needs to know your timezone.

In which case, the label should be more like:

"Specify your timezone (for weird technical reasons you don't need to know.)"

Because that is *all* the user needs to know: what is your timezone. Everything else is complex detail that the code and the developer knows about. And hides from the user.
