You can include daylight saving time definitions when defining a time zone. To do so, define a time zone with the following statement:

In the preceding syntax statement

• LOCAL is a special time zone definition that specifies the parameter as relative to the local computer where Control-M is operating

  A LOCAL definition is needed only when specifying a daylight savings time range for the local time zone.

• xxx, hh and mm are the time zone code, hours, and minutes as described in Standard Time Zone Definitions
• In a FROM or TO clause, date is the date (the DD.MM or MM.DD depending on the installation date format DATETYP) when the clock time is changed
• In a FROM or TO clause, hh and mm are the time in hours and minutes when the clock time is changed, each expressed as a 2-figure number

In all daylight saving time zone definitions, the first time period relates to the winter zone and the second time period relates to the summer zone. A zone cannot span over the end of the calendar year (for example, you cannot define a zone that starts in November and ends in February).

The FROM keyword defines the beginning of the daylight saving time period, and the TO keyword defines the end of the daylight saving time period. The first GMT clause defines the standard (non-daylight saving time) difference between the local time and GMT, while the second GMT clause (the one after the TO clause) defines the time difference during the daylight saving period (the dates between the FROM and TO statements.

You can define a time zone without a daylight saving time zone definition. However, when you use the FROM keyword, you must then enter a full daylight saving time definition, including the TO keyword as well as the FROM keyword.
