Hi,I know, this is a very extensive question. But I think that this is the best way to get a meaningful answer. My company is situated in Germany and so we are subjected to the rearrangement of the summertime. And so we had last monday the catastrophe. All our "NTP-clients" were with one our out of sync. This is our configuration: NTP-Server: Windows 2003 Standard Server with ServicePack 1 Tobit Time:LAN! DCF77 receiver NTP-Clients: - ADS-domain with two controllers - Solaris-server - Redhat-server - AIX-server Before the rearrangement of the summertime, the time-settings of the NTP-server: Timezone: GMT+1 with automatic winter-/summertime-rearrangement ADS-server and -clients: Timezone: GMT+1 with automatic winter-/summertime-rearrangement Solaris-server: Timezone: MET and Europe/Berlin Redhat-server: Timezone: Europe/Berlin AIX-server: Timezone: NFT with automatic winter-/summertime-rearrangement So that the authentication in the ADS-domain and the NTP-synchronization with the correct daytime functioned after the rearrangement of the summertime, we changed the time-settings of the NTP-server: Timezone: GMT+1 ADS-server and -clients: Timezone: GMT+1 Solaris-server: Timezone: MET-1 Redhat-server: Timezone: GMT-1 AIX-server: Timezone: NFT So, know what will happen in October when the wintertime will get active again? And did we perhaps choose the wrong way in the way we "solved" the problem?
NTP should not be part of your problem. NTP concerns itself ONLY with UTC. The time displayed by the computer should be UTC +/- the offset appropriate for the timezone you have selected.
How the operating system handles timezones is specific to the O/S. You will not find much help here with setting the timezone or even which timezone to set.
It may also be worth noting that Windows does not use NTP software; Microsoft supplies a broken implementation of SNTP called W32TIME. NTP software is available for Windows if you wish to download and install it.
