The server sets the cookie expiration, using time/date in GMT. The browser just stores that and everytime a page matches that cookie it is returned. I don't know that the browser expires the cookie or if the server stops accepting the cookie after the exipiration time (and from the standpoint of my code, I don't care either).In any case, the time that the cookie expires is based on the server's time, not the client's time, as translated to GMT.> > I must be missing something then.

You can only access local time on the server, which does change based on whether DST is in effect. Thus, there is a need to know when your offset to GMT changes. One simplistic way to deal with this is to change the server's timezone to GMT and always return GMT times.John-- John Peacock Director of Information Research and Technology Rowman & Littlefield Publishing Group 4720 Boston Way Lanham, MD 20706 301-459-3366 x.5010 fax 301-429-5747 ------------------------------------------------------------- This message is sent to you because you are subscribed to the mailing list
