Hello.
My Mac can't detect a correct time from Windows AD server. If my Windows server time is 13:00 PM, Apple show me 14:00 PM. I changed "ntp.conf" file and introduce my Windows server too but problem not solved.
I used below command to but problem not solved :

ntpdate -u "my windows server"

at the final I used "www.pool.ntp.org/zone/asia" and copy and paste the below server into "ntp.conf" but problem exist :

server 0.asia.pool.ntp.org
server 1.asia.pool.ntp.org
server 2.asia.pool.ntp.org
server 3.asia.pool.ntp.org

How can I solve it?

Perhaps it might be that your Mac is setup in another time zone?

No, Time zone is correct and I also disable automatic detect location.

Might be something related to DST.

The proper way to set your time server in OS X is to use:

systemsetup -setnetworktimeserver yourtimeserverhere

The man page for systemsetup has several other options. You'll want to ensure that

systemsetup -setusingnetworktime on

is set.
Are you certain that the Mac can actually resolve the time server?

Does the Mac set the time properly using time.apple.com? If it does, then you know that your Mac is not the problem and one, some, or all of the following are true:

1. The AD server isn't running NTP.
2. The Mac cannot resolve the hostname of your time server.
3. The Mac cannot connect to the time server due to network configuration.

If NTP not running How Windows client sync time?
Mac can detected my network because of it is part of my networked and joined into AD.

I'm offering suggestions to test, not telling you what's wrong. Again, can the Macs properly sync time from time.apple.com? You need to do some basic troubleshooting.
