Time zones
Use this function to define world time zones.
World time zones are used to convert dates and times sent to Production Scheduler to the primary time standard "UTC" (Coordinated Universal Time).
UTC (Coordinated Universal Time) is the equivalent of GMT/GT (Greenwich Mean Time/Greenwich Time).
The rules that determine when Daylight Saving Time (DST) starts or ends can change, and for some time zones changes every year. For Production Scheduler to correctly convert between a time zone and UTC you enter and update time zone information using a set procedure, as follows - you must be careful to make changes in the order below:
- Define the world time zones.
You define world time zones in this function (TIMEZONEINFO).
Once defined, you must set the PSTIMEZONE - Server time zone parameter (EXAPP chapter, MIS group) to the time zone in which your server is located. - Define daylight Saving Time (DST) transition rules for world time zones in the Change to daylight saving time function (TIMETRANS).
- Define transition rules to Daylight Saving Time (DST) across world time zones in the Adjustment rules of daylight saving time function (TIMEADJUST).
Refer to documentation Screen management
The Time zones function displays existing time zones in a grid, or table.
Presentation
Each line of the table represents a world or regional time zone with the UTC offset defined.
The time zones are used by the system to convert dates and times sent to Production Scheduler to the primary time standard "UTC" (Coordinated Universal Time).

|
Use this field to identify an official time zone name. A time zone generally refers to the local time of a region or a country. For example, "ACWST" or "Aus Central W. Standard Time". |
|
|
Use this field to describe this time zone. You might include the time zone name if you used the abbreviation for the Code field or the official abbreviation for this time zone. For example, "ACWST - Aus Central W Standard" or "AUS Central West Standard Time". |
|
|
Use this field to describe this time zone. You might include the full time zone name or a reference to the UTC offset for a location in this time zone. For example, "ACWST - Australian Central Western Standard Time" or "(UTC+08:45) Eucla". |
|
|
Use this field to define the offset (the difference) for this local time or time zone from Coordinated Universal Time (UTC), the world's time standard. If this time zone is behind UTC, prefix the figure with a minus sign ("-").
|
|
|
If this time zone observes Daylight Saving Time (DST) during the summer, use this field to define the time zone name (Code field) this time zone uses in the summer. This can be the same time zone as the time zone defined in the Code field (COD). |

Examples
By its own definition, a time zone standard time or Daylight Saving Time (DST) will change.
The following scenarios demonstrate when DST changes are required and which functions to use.
- The daylight-saving time transition day changes:
- Use the Change to daylight saving time function (TIMETRANS) to add a new transition rule, if required.
- Use the Adjustment rules of daylight saving time function (TIMEADJUST) to add a new adjustment rule.
- A new time zone is created for your location:
- Use the Change to daylight saving time function (TIMETRANS) to add a new transition rule, if required.
- Use the Adjustment rules of daylight saving time function (TIMEADJUST) to add a new adjustment rule.
- Use the Time zones function (TIMEZONEINFO) to add the new time zone.
- Your time zone stops using DST:
- Use the Adjustment rules of daylight saving time function (TIMEADJUST) to add a new adjustment rule.
- Your time zone starts using DST:
- Use the Change to daylight saving time function (TIMETRANS) to add a new transition rule, if required.
- Use the Adjustment rules of daylight saving time function (TIMEADJUST) to add a new adjustment rule.
- Use the Time zones function (TIMEZONEINFO) to reference the new adjustment rule (in the Daylight saving time field (TADCOD)).
