The Indiana Time Zone is changing and will now reflect the daylight savings time. Netware and GroupWise need to be updated!


Before you begin - read the following critical information ...

It's important that you have your hardware clock set (whether by DOS or another means) before you bring your server up. This will ensure that you have the least amount of time variance - especially in a multi-server environment.

If you are running eDirectory on a multi-server network, changing a secondary server's time may not be desirable. That's because you run the risk of throwing that server into "synthetic time." Changing the time on the Primary time server can cause problems if the time is set behind any secondary servers that are getting their time from this Primary time server. You then also run the risk of throwing the servers into synthetic time.

Synthetic time occurs when time synchronization is lost because the server's local time has been set backwards. Synthetic time is the process of creating timestamps from the most recent timestamp in eDirectory. From this timestamp, the event counter increments until it reaches 65,535 events, then another second is added to time and the event counter continues to increment. This process continues until real time catches up with the synthetic time stamps being used.

Procedures for Changing the Time Zone

A: Changing the Time Zone settings on the Server to Eastern with DST

1. Load Monitor.

2. Go to Server Parameters > Time and modify the following settings:

  a. Start of Daylight Savings Time: (April Sunday First 2:0:0 am) 
  b. End of Daylight Savings Time: (October Sunday Last 2;0:0 am) 
  c. Daylight Savings Time Offset - +1:00:00 
  d. Time Zone - EST5EDT 

3. Change your AUTOEXEC.NCF and add each of the following SET commands to the top of the file:

  a. SET TIME ZONE = EST5EDT   b. SET Daylight Savings Time Offset = +1:00:00   c. SET Start Of Daylight Savings Time = (April Sunday First 2:0:0 am)   d. SET End Of Daylight Savings Time = (October Sunday Last 2:0:0 am)

4. Save your changes and exit.

5. Escape out and save.
