curl_getdate

curl_getdate(3) 						  libcurl Manual						   curl_getdate(3)

NAME

       curl_getdate - Convert a date string to number of seconds since January 1, 1970

SYNOPSIS

       #include <curl/curl.h>

       time_t curl_getdate(char *datestring, time_t *now );

DESCRIPTION

       This  function returns the number of seconds since January 1st 1970 in the UTC time zone, for the date and time that the datestring parame-
       ter specifies. The now parameter is not used, pass a NULL there.

       NOTE: This function was rewritten for the 7.12.2 release and this documentation covers the functionality of the new one. The new one is not
       feature-complete with the old one, but most of the formats supported by the new one was supported by the old too.

PARSING DATES AND TIMES

       A  "date"  is  a  string containing several items separated by whitespace. The order of the items is immaterial.  A date string may contain
       many flavors of items:

       calendar date items
	       Can be specified several ways. Month names can only be three-letter english abbreviations, numbers can  be  zero-prefixed  and  the
	       year may use 2 or 4 digits.  Examples: 06 Nov 1994, 06-Nov-94 and Nov-94 6.

       time of the day items
	       This string specifies the time on a given day. You must specify it with 6 digits with two colons: HH:MM:SS. To not include the time
	       in a date string, will make the function assume 00:00:00. Example: 18:19:21.

       time zone items
	       Specifies international time zone. There are a few acronyms supported, but in general you should instead use the specific  relative
	       time compared to UTC. Supported formats include: -1200, MST, +0100.

       day of the week items
	       Specifies  a  day  of the week. Days of the week may be spelled out in full (using english): `Sunday', `Monday', etc or they may be
	       abbreviated to their first three letters. This is usually not info that adds anything.

       pure numbers
	       If a decimal number of the form YYYYMMDD appears, then YYYY is read as the year, MM as the month number and DD as the  day  of  the
	       month, for the specified calendar date.

STANDARDS

       This  parser  was  written to handle date formats specified in RFC 822 (including the update in RFC 1123) using time zone name or time zone
       delta and RFC 850 (obsoleted by RFC 1036) and ANSI C's asctime() format. These formats are the only ones RFC2616 says HTTP applications may
       use.

RETURN VALUE

       This function returns -1 when it fails to parse the date string. Otherwise it returns the number of seconds as described.

       If  the	year  is  larger than 2037 on systems with 32 bit time_t, this function will return 0x7fffffff (since that is the largest possible
       signed 32 bit number).

       Having a 64 bit time_t is not a guarantee that dates beyond 03:14:07 UTC, January 19, 2038 will work fine. On systems with a 64 bit  time_t
       but with a crippled mktime(), curl_getdate will return -1 in this case.

REWRITE

       The  former version of this function was built with yacc and was not only very large, it was also never quite understood and it wasn't pos-
       sible to build with non-GNU tools since only GNU Bison could make it thread-safe!

       The rewrite was done for 7.12.2. The new one is much smaller and uses simpler code.
