What files need to be updated on Control-M when the Time Zone or Daylight Savings information changes?

Where is the TimeZone.dat file for Control-M Server, Control-M Enterprise Manager (EM) Server and Control-M Enterprise Manager (EM) Client?

Time Zone information changes in some countries and it is necessary to modify and synchronize the TimeZone.dat file on the Control-M/Server, Control-M/Enterprise Manager Server and Control-M/Enterprise Manager Client for jobs to be scheduled correctly.
Note:
- If the Timezone.dat file on Control-M EM Server, Control-M EM Client, and Control-M Server are out of synch, unpredictable results can occur for Control-M Forecast & Batch Impact Manager and will not reflect the correct times for jobs/services.
- Documentation on DST support can be found in the Admin Guide

4. Edit the TimeZone.dat file, adding or changing TimeZones as necessary
5. Save the TimeZone.dat file

For Unix-based Control-M/Enterprise Manager Servers

1. Login to the Control-M/Enterprise Manager as the Control-M/Enterprise Manager user
2. Navigate to the <em_home>/etc/cli/data directory
3. Make a backup copy of the existing TimeZone.dat file
4. Edit the TimeZone.dat file, adding or changing TimeZones as necessary

Instructions for version 9.0.21 and up can be found here :

For Control-M/zOS

1. refer to Documentation for instructions

In Control-M/Enterprise Manager versions 9.0.00 and later using Linux, there is an additional TimeZone.dat file located in the ~ctm_em/data/validation directory. It will be necessary to update this file as well.

For more information on TimeZone support, please refer to the Control-M Administrator Guide.

Additional Information:
The Control-M/Server does not have to be cycled for the change to take effect
Due to an issue with Control-M/Server, it must be recycled or the updated TimeZone.dat file will not be used for versions prior to 9.0.21.300
CTM-5009 has been created for this issue and is implemented in version 9.0.21.300, no longer requiring a restart of Control-M/Server.
