Detect user's local system time

what are the options?

[Purple Martin]

Is there any way to detect a user's local system time (so that I can make server-side time zone corrections)? I can't find a relevant field in the HTTP request header for this.

I don't want to use an applet or an ActiveX if I can help it, and I don't want to use JavaScript with a re-request if I can help it.

Any ideas?

Not that I know of. You have to somehow "ask" the client what time it is. It doesn't just tell you, and you're correct, no HTTP headers sent by the client that read "it's beer:thirty in paradise." :-)
