Actually, seeing it explained that way simplifies it in my mind, at least for the domain time synchronization issue. The workstation syncs its time to the server in UTC time, and then it adjusts that according to its own time zone setting and time zone rules (such as DST) to get the current local time. Now that you describe it, it's obvious that this is how it would have to work, unless Microsoft was going to make the assumption that all workstations are always in the same time zone as their server. So to keep the workstation time accurate automatically even in a domain, it is necessary that each workstation know the correct DST rules. > -----Original Message----- > From: Hoort, Brian [mailto:[log in to unmask]] > Sent: Friday, February 16, 2007 8:03 PM > To: [log in to unmask] > Subject: Re: [MSUNAG] DST 2007 on Windows 2000 > > Regarding domain workstations syncing with their DCs for > time, we were thinking yes, they will.
