error

indicates the outcome of the operation. Table 4-2, Error Summary for DST_*

Procedures, summarizes the possible values for error. It is recommended that

the literal values be used instead of the numerical values when coding (for

example, ZSYS^VAL^DST^OK, not 0).

keygmt input

FIXED:value

specifies time in GMT for required DST information. If

keygmt is set to 0, it

returns the entry currently in effect. If

keygmt is set to -1, it returns the first entry in

the table. If

keygmt is set to 1, it returns the last entry in the table.
