NTP & Time Zones
With the upcoming DST issues it's worth remembering how NTP works.
NTP and SNTP both work in the same way, time is pulled from a time source (generally a server on the Internet) as UTC time. The Operating System THEN applies any change relevant to the time zone that the server lives in. NTP cannot and will not change any clock on a server or other operating system, this is something the application must deal with itself.
Tomorrow I will cover how this problem affects Windows and other various applications as well as provide a download for Windows 2000 machines which Microsoft no longer support for anything other than security updates.
