Library: General, Date and time functions (OMDATE) Include: omdate.xin

Return type: String Returns:  Returns the specified date in "YYYYMMDDhhmmss+ZHZM" format.

Declaration

  define stream function arpadate-to-ymdhms value stream arpadate

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

Argument:

• "arpadate" -- a date in standard ARPA/Internet RFC-822 format.

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
