Time Zone Configuration Issues

January 17, 2008

Hello, folks.

I've been researching on a script to enable the daylight savings

configuration and synchronize the system time of all machines in the domain

with one of the DCs (PDC emulator).

The .vbs script worked fine on all tests and we finally decided to apply it

through a GPO to the domain.

First we manually did all the servers and double checked whether the summer

times were all correct.

Then we applied the GPO. It did enable the daylight option on the stations

and also updated the time.

Thats when the problems begun.

We are normally GMT -3. With daylight savings, we turn to GMT -2.

Thing is, the machines can only get GMT -3 from the servers. Meaning they

are 1 hour behind all the servers.

When I run "net time" on any machine, this message comes up:

_____________________________________________________

The current time at \\server1 is 1/16/2008 7:50 AM

The local time (GMT -02:00) at \\server1 is 1/16/2008 8:50 AM

_____________________________________________________

Apparently the stations see that the "real" time on the server is not the

daylight savings one and synchronize with that "real" time.

Another detail is that the time zone on all machines and servers is GMT - 3

but on the message, it said GMT -2.

If I disable the daylight option on the server, the machines manage to

synchronize OK.

Has anyone ever seen this before?

Any ideas on how to synchronize correctly the times?

Thanks very much, guys!

Demerson.
