!!! Overview
Many [network] [services] are [dependent on time synchronization|[Why is Time Important].This is a short [Cheat Sheet] to [{$pagename}]
! Verify Time Windows
You can manually synchronize a computer with the time on the domain.
To force synchronize the computer's time manually with the current time on the domain
* Click Start
* click Run.
* net time /domain /set
* click OK.
You can also monitor the time by using:
{{{
w32tm /monitor
SERVER1.yourdomain.com[10.178.136.20:123]:
ICMP: 40ms delay
NTP: -0.0151674s offset from SERVER1.yourdomain.com
RefID: server.yourroot.com [10.92.180.175]
Stratum: 3
SERVER2.yourdomain.com[10.182.255.64:123]:
ICMP: 20ms delay
NTP: +0.0074253s offset from SERVER2.yourdomain.com
RefID: server.yourroot.com [10.92.180.175]
Stratum: 3
SERVER3.yourdomain.com *** PDC ***[10.92.180.167:123]:
ICMP: 3ms delay
NTP: +0.0000000s offset from SERVER3.yourdomain.com
RefID: server.yourroot.com [10.92.180.175]
Stratum: 3

! Verify Time Linux
For most Linux and UNIX hosts:
{{{
ntpq -p
remote refid st t when poll reach delay offset jitter

! [EDirectory] Tree
You should regularly check that [Time sync] is correct within your [EDirectory] Tree
We use the following command:
{{{
/opt/novell/eDirectory/bin/ndsrepair -T
}}}
Typical output is:
{{{
---------------------------+---------+---------+-----------+--------+-------
DS Replica Time Time is Time
Server name Version Depth Source in sync +/-
---------------------------+---------+---------+-----------+--------+-------
Processing server: .bratton.srv.willeke.com
.bratton.srv.willeke.com 20601.18 0 Non-NetWare Yes 0
Processing server: .sa.svr.willeke.com
.sa.svr.willeke.com 20601.18 0 Non-NetWare Yes 0
---------------------------+---------+---------+-----------+--------+-------
}}}
All servers shown in the time sync screen should show as YES
NOTE: vmware servers or servers on wan link may be shown as not in (quite) sync.
Many people use [NTP] others use [SNTP] to maintain [Time sync].
