Defining Daylight Savings Time support

This procedure describes how to define Daylight Savings Time (DST) support from the TimeZone.dat file. You only need to do this procedure if the Control-M/Server resides in a location where DST is used.

To define Daylight Savings Time support:

1. Navigate to the following directories, and complete this procedure for each TimeZone.dat file:
   • <ctm_server_home>/data
   • *<*em_home>/ctm_em/data/

   The standard format for the definition is timeZone (GMT±hh:mm), where timeZone represents the time zone label.

   EXAMPLE: The label EST represents the Eastern Standard time zone, and the regularly formatted entry for the Eastern Standard Time time is EST GMT -05:00.

2. Change the relevant time zone definition so that it includes DST adjustments., as follows:

   timeZone (GMT±hh:mm) FROM dd.mm hh:mm TO dd.mm hh:mm (GMT±hh:mm)

   Where::

   • timeZone (GMT±hh:mm) indicates the regular time zone value (for example, CET (GMT+02:00) )
   • FROM and TO values indicate the time frame during which DST is in effect. (For example, FROM 01.03 01:59 TO 24.10 02:00)
   • The second GMT value indicates the DST time-offset relative to GMT (for example,(GMT+03:00))

   NOTE:

   • This syntax is reversed for the southern hemisphere. The FROM and TO keywords specify the start and end settings for daylight saving to take effect.
   • There must be an empty line at the end of the file.

   EXAMPLE: Bill needs to create a new time zone label for Japan, where the time is nine hours later than Greenwich Mean Time (GMT). DST begins March 1 at 01:59 and ends October 24 at 02:00. Bill uses the following entry to create the new label (JST):

   JST (GMT+09:00) FROM 01.03 01:59 TO 24.10 02:00 (GMT+10:00)

   EXAMPLE: Although time zone definitions in the northern hemisphere are set to summer Daylight Saving Time, definitions in the southern hemisphere are set to winter. In Sydney, Australia, winter time (GMT+09:00) is from March 25 at 03:00 until October 1 at 02:00. All other dates are GMT+10:00 (summer time). The time label for Sydney is defined as follows:

   SYD (GMT+11:00) FROM 25.03 03:00 TO 01.10. 02:00 (GMT+10:00)

   NOTE: If a relevant time zone contains several countries, some observe DST and some do not (or if they change the clock on different days) add additional time zone definitions to cover the variations.

3. Recycle Control-M/Server.
4. Update the relevant job processing definitions, using the appropriate variations.

   NOTE: If you delete a time zone from TimeZone.dat or modify a three-character name in that file, change any job processing definitions that specify that time zone. Otherwise, those job processing definitions are invalid.
