How to Change or Set Network Time.


Novell NetWare 6.0

Novell NetWare 5.1

Time is in sync on the network.


Time on the network is not correct.


Time on the time provider has slowed or is incorrect.


Warning:  Changing time forward, then back on a NetWare tree can have serious repercussions.  Do not set time forward and then back on a production tree for testing purposes.  If time is set forward and timestamps are incremented (last login, etc.) you will receive synthetic time.  Synthetic time is not covered within this solution.   See Solutions:  Synthetic time: summary, (Solution  4.0.14774022.2262591)., What is Synthetic Time? (Solution 1.0.56379119.2545508), and "Time is not synchronized to the network" (3.0.339019.2205465) for problems with synthetic time.

Warning:  Do not move time back on your network until after you are prepared to deal with synthetic time issues and thoroughly understand the issues involved with synthetic time.

If time needs to indeed be set, it should be done from the Single Reference or Reference time server.  Setting time from a Primary or Secondary time server will only result in unexpected results in the time being changed again if a difference in time is found on the next polling interval.  

To set time on a network go to Monitor - Server Parameters - Time -  on the time provider. In the TIMESYNC TIME ADJUSTMENT field enter the amount of time and direction to move time:


The change will occur 1 hour later by default, you can add AT DATE and TIME to schedule it if desired. The command can also be issued on the command line using the same syntax, for example:

SET TIMESYNC TIME ADJUSTMENT = +00:00:10 AT MAY 29, 2003 4:47:00 PM PDT

If time is moved forward on the network there should be no errors reported.  If time was moved backward, Synthetic time will be issued on the partition until the timestamp that is future in the partition(s) is reached.
