  omdate - date and time functions    

The functions in this library define a set of operations on dates and times. They are built around a standard normalized form for the date/time, a 19-character string in "YYYYMMDDhhmmss+ZHZM" format where:

The response to erroneous argument values in these functions is to return a conventional value: for "stream" valued results this is always the string "???", and for "counter" valued results this is 0 (zero) for differences or 1 (one) for counts.

To use this library in a program, you must include the following code near the top of your program:

  ; Date and Time function and constant declarations
  include "omdate.xin"
