Library: omdate - date and time functions Include: omdate.xin

Return type: String Returns:        Returns the specified date/time rounded down to the nearest indicated interval.

Declaration

  define stream function round-down-ymdhms value stream ymdhms
                                        to value stream interval

This function takes a date/time in "YYYYMMDDhhmmss+ZHZM" format, and returns the same value but rounded down to the beginning of an interval indicated by the second argument.

Arguments:

• "ymdhms" -- a date/time in "YYYYMMDDhhmmss+ZHZM" format.
• "interval" -- the name of the interval which you want the indicated date rounded to. For example, "year", "month", "day", "hour", or "minute". Only the shortest distinguishing prefix of the interval name is needed, so "y" can be used in place of "year", but "mo" and "mi" are needed to distinguish between "month" and "minute". This argument can be in either uppercase or lowercase. If this argument is unrecognized, the date/time will be returned unchanged.

Example:

  include "omdate.xin"
  process
     local stream now
     set now to now-as-ymdhms
      output "Now, unrounded                  = "
         || now
         || "%n"
         || "Now, rounded down to the minute = "
         || round-down-ymdhms now to "mi"
         || "%n"
  ; Results of this program were:
  ;    Now, unrounded                            = 20010215162804-0500
  ;    Now, rounded down to the minute = 20010215162800-0500
