Declaration

  define stream function add-to-ymdhms
                          value stream ymdhms
                   years value integer years-to-add optional initial {0}
                  months value integer months-to-add optional initial {0}
                    days value integer days-to-add optional initial {0}
                   hours value integer hours-to-add optional initial {0}
                 minutes value integer minutes-to-add optional initial {0}
                 seconds value integer seconds-to-add optional initial {0}

This function takes a date/time in "YYYYMMDDhhmmss+ZHZM" format and any number of values to add or subtract from the given date/time. After the new date/time has been calculated, it is returned in "YYYYMMDDhhmmss+ZHZM" format.

Arguments:

• "ymdhms" -- the initial date/time in "YYYYMMDDhhmmss+ZHZM" format.
• "years-to-add" -- a signed numeric value representing the number of years you wish to add or subtract from the initial date/time.
• "months-to-add" -- a signed numeric value representing the number of months you wish to add or subtract from the initial date/time.
• "days-to-add" -- a signed numeric value representing the number of days you wish to add or subtract from the initial date/time.
• "hours-to-add" -- a signed numeric value representing the number of hours you wish to add or subtract from the initial date/time.
• "minutes-to-add" -- a signed numeric value representing the number of minutes you wish to add or subtract from the initial date/time.
• "seconds-to-add" -- a signed numeric value representing the number of seconds you wish to add or subtract from the initial date/time.

Note that all except the "ymdhms" argument are optional, and that the default value of all optional arguments is 0 (zero).

Example:

  ; Add one year to the current date 
    include "omdate.xin"
    process
      local stream ymdhms  ; current date
      local integer years-to-add initial {1}
      local stream incremented-date
      set ymdhms to now-as-ymdhms
      set incremented-date to add-to-ymdhms ymdhms years years-to-add
      output "Current date          = " || ymdhms || "%n"
      output "Current date + 1 year = " || incremented-date
  ; Result of this example:
  ;      Current date          = 20010214155655-0500
  ;      Current date + 1 year = 20020214155655-0500
