DST_TRANSITION_ADD_ Procedure
Structure Definition for dstentry
The dstentry parameter specifies the attributes of the new process.
In the TAL ZSYSTAL file, the structure for the
dstentry parameter is defined as:
Z^LOWGMT
identifies the lower limit of the interval in Greenwich Mean Time (GMT).
Z^HIGHGMT
identifies the higher limit of the interval in GMT.
Z^OFFSET
identifies the offset value of a transition.
Z^VERSION
identifies the version of the ZSYS^DDL^DST^ENTRY^DEF structure.
Z^FILLER
is provided for future use.
Considerations
•
All time intervals that do not have explicit nonzero offset transition added are
assumed to have a zero offset. Furthermore, all intervals that have a zero offset
transition do not need to be explicitly added.
•
All intervals that have nonzero offset transition must be explicitly added.
•
Transitions can be added only if the interval that is to be added is completely
covered by a zero offset interval in the table.
