NAME

APR::Date - Perl API for APR date manipulating functions

Synopsis

   use APR::Date ();
   
   # parse HTTP-complient date string
   $date_string = 'Sun, 06 Nov 1994 08:49:37 GMT';
   $date_parsed = APR::Date::parse_http($date_string);
   
   # parse RFC822-complient date string
   $date_string = 'Sun, 6 Nov 94 8:49:37 GMT';
   $date_parsed = APR::Date::parse_rfc($date_string);

Description

"APR::Socket" provides the Perl interface to APR date manipulating functions.

API

"APR::Date" provides the following functions and/or methods:

parse_http

Parse HTTP date strings 
   $date_parsed = parse_http($date_string);
arg1: $date_string ( string )
The date string can be in one of the following formats: 
   Sun, 06 Nov 1994 08:49:37 GMT  ; RFC 822, updated by RFC 1123
   Sunday, 06-Nov-94 08:49:37 GMT ; RFC 850, obsoleted by RFC 1036
   Sun Nov  6 08:49:37 1994       ; ANSI C's asctime() format

refer to RFC2616 for the details (GMT is assumed, regardless of the used timezone).

ret: $date_parsed ( number )
the number of microseconds since 1 Jan 1970 GMT, or 0 if out of range or if the date is invalid.
since: 2.0.00

Remember to divide the return value by 1_000_000 if you need it in seconds.

parse_rfc

Parse a string resembling an RFC 822 date. It's meant to be lenient in its parsing of dates. Hence, this will parse a wider range of dates than "parse_http()". 
   $date_parsed = parse_rfc($date_string);
arg1: $date_string ( string )
The date string can be in one of the following formats: 
   Sun, 06 Nov 1994 08:49:37 GMT  ; RFC 822, updated by RFC 1123
   Sunday, 06-Nov-94 08:49:37 GMT ; RFC 850, obsoleted by RFC 1036
   Sun Nov  6 08:49:37 1994       ; ANSI C's asctime() format
   Sun, 6 Nov 1994 08:49:37 GMT   ; RFC 822, updated by RFC 1123
   Sun, 06 Nov 94 08:49:37 GMT    ; RFC 822
   Sun, 6 Nov 94 08:49:37 GMT     ; RFC 822

   Sun, 6 Nov 94 8:49:37 GMT      ; Unknown [Elm 70.85]
ret: $date_parsed ( number )
the number of microseconds since 1 Jan 1970 GMT, or 0 if out of range or if the date is invalid.
since: 2.0.00

Remember to divide the return value by 1_000_000 if you need it in seconds.
