returns 5 for HOUR.
XDATE.MINUTE(arg) Return the minute of the hour from a date or time of day. The result is
an integer from 0 through 59. For example, you can extract the minute

returns 30 for MIN.
XDATE.SECOND(arg) Return the second of the minute from a date or time of day. The result is
an integer or, if there are fractional seconds, a value with decimals. For

When the value for BIRTHDAY is 05-DEC-1954 5:30:15, this command
returns a value of 15.00 for SEC.
XDATE.WKDAY(arg) Return the day within a week from a date. The result is an integer between
and including 1 and 7, with Sunday being 1 and Saturday being

you can extract the day of the week from BIRTHDAY, as in
COMPUTE DAYNAME=XDATE.WKDAY(BIRTHDAY).
When the value for BIRTHDAY is 05-DEC-1954 5:30:15, this command
returns the value 1 for DAYNAME. If you provide an output format of
WKDAY, as in
PRINT FORMAT DAYNAME (WKDAY9).

XDATE.JDAY(arg) Return the day of the year from the date. The result is an integer
between 1 and 366 inclusive. The date must have occurred after
October 14, 1582. For example, you can extract the day of the year

When the value for BIRTHDAY is 05-DEC-1954 5:30:15, this command
returns the value 339 for DAYNUM.
XDATE.QUARTER(arg) Return quarter number within a year for a date. The result is 1, 2, 3,
or 4. The date must have occurred after October 14, 1582. To extract
