Argument definitions

arpadate: a date in standard ARPA/Internet RFC-822 format

Purpose

This function takes a date/time in standard ARPA/Internet RFC-822 format and returns it in "YYYYMMDDhhmmss+ZHZM" format. Considerable flexibility is allowed by RFC-822, and additionally, this function allows further laxity in the ARPA date/time format:

extra and missing white space is allowed
month names and time zones are not case sensitive
the day, hour, minute, and second can have one or two digits in them
the colons in the time part are optional, or can be dashes
two-digits years are allowed -- 70 to 99 are assumed to be 1970 to 1999, and 00 to 69 are assumed to be 2000 to 2069

Example:

  ; Takes ARPA/Internet RFC-822 date format and returns it in "YYYYMMDDhhmmss+ZHZM" format. 
    include "omdate.xin"
    process
      local stream my-date  ; YYYYMMDDhhmmss+ZHZM format date
      local stream input-arpadate initial {"20 Feb 01 21:38:23"}
      set my-date to arpadate-to-ymdhms input-arpadate
      output "input-arpadate = " 
         || input-arpadate
         || "%n"
         || "my-date = " 
         || my-date
         || "%n"
  ; Result of this code:
  ;    input-arpadate = 20 Feb 01 21:38:23
  ;    my-date = 20010220213823+0000
