Argument definitions

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


Purpose

Use add-to-ymdhms to take the starting date ymdhms and calculate a new date from it. The new date/time is returned in YYYYMMDDhhmmss+ZHZM format.

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

Example

The following program takes the current date and adds one year to it. 

  include "omdate.xin"
  
  process
     local integer years-to-add initial {1}
     local string  ymdhms
     local string  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
Running this example program might yield output such as 
  Current date          = 20191031153022-0400
  Current date + 1 year = 20201031153022-0400

Usage Note

To use add-to-ymdhms, you must include the following code near the top of your program: 

  include "omdate.xin"
