Subject Re: Getting the date/time from the client
Date Tue, 11 Jul 2006 09:40:58 GMT
uh...
no luck yet. getDateHeader only returns the date value when
you have some query strings in date format.
So, send the time as a part of query string like this
index.jsp?requesttime="25:40:12" or something similar.

If one has a better solution let him know.
