NTP Server Using Different Timezones

Vihang. — Mon, 25 Aug 2008 10:43:15 GMT

Hello Experts,

I need to configure NTP using below setup.

There are 6 servers in India out of which 1 server will become the NTP server for the other 5. The NTP server from India uses IST (India Standard Time) & it should take its time from a central NTP server which is located at Singapore & uses SST (Singapore Standard Time). So the Singapore server will be the NTP server for the NTP server at India & rest all servers at India will take time from the India NTP server.
My questions are,
1) Is it possible to configure?
2) If yes, how to do it?
3) Will the server be able to sycnronize its time across different timezones?

Thanks & Regards,
Vihang.

Hi:

Your assumption is wrong. NTP works in UTC (GMT) time. It is *your* server, using one or *more* 'TZ' settings that expresses the concept of localtime as a positive or negative offset from the UTC time.

The configuration of NTP is simple:

Choose at least three time sources. A pool of servers from which to select can be found here:

Local time is displayed according to the TZ setting on your particular server. Even different users on the same machine can have different TZ settings and the time will appear differently for each. Thus timezones have no influence over NTP setup.

As far as implementing NTP, use SAM > Time > NTP Broadcasting (for the server) and > NTP Network Time Sources (for the clients).
