APR::Date - Perl API for APR date manipulating functions
=head1 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);
=head1 Description
C<APR::Socket> provides the Perl interface to APR date manipulating
functions.
=head1 API
C<APR::Date> provides the following functions and/or methods:
=head2 C<parse_http>
Parse HTTP date strings
$date_parsed = parse_http($date_string);
=over 4
=item arg1: C<$date_string> ( string )
The date string can be in one of the following formats:
Sun, 06 Nov 1994 08:49:37 GMT ; RFC 822, updated by RFC 1123
Sunday, 06-Nov-94 08:49:37 GMT ; RFC 850, obsoleted by RFC 1036
Sun Nov 6 08:49:37 1994 ; ANSI C's asctime() format
refer to RFC2616 for the details (GMT is assumed, regardless of the
used timezone).
=item ret: C<$date_parsed> ( number )
the number of microseconds since 1 Jan 1970 GMT, or 0 if out of range
or if the date is invalid.
=item since: 2.0.00
=back
Remember to divide the return value by 1_000_000 if you need it in
seconds.
=head2 C<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 C<L<parse_http()|/C_parse_http_>>.
$date_parsed = parse_rfc($date_string);
=over 4
=item arg1: C<$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
