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()|/C_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, 06 Nov 94 08:49 GMT       ; Unknown [drtr\@ast.cam.ac.uk]
  Sun, 6 Nov 94 08:49 GMT        ; Unknown [drtr\@ast.cam.ac.uk]
  Sun, 06 Nov 94 8:49:37 GMT     ; Unknown [Elm 70.85]
  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.
