.SH NAME
|
||||
curl_getdate - Convert a date string to number of seconds
|
||||
.SH SYNOPSIS
|
||||
.B #include <curl/curl.h>
|
||||
.sp
|
||||
.BI "time_t curl_getdate(char *" datestring ", time_t *"now " );"

|
||||
.SH DESCRIPTION
|
||||
\fIcurl_getdate(3)\fP returns the number of seconds since the Epoch, January
|
||||
1st 1970 00:00:00 in the UTC time zone, for the date and time that the
|
||||
\fIdatestring\fP parameter specifies. The \fInow\fP parameter is not used,
|
||||
pass a NULL there.
|
||||
.SH 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:
|
||||
.TP 0.8i
|
||||
.B 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.
|
||||
.TP
|
||||
.B 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.
|
||||
.TP
|
||||
.B 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.
|
||||
.TP
|
||||
.B 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.
|
||||
.TP
|
||||
.B 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.

.SH 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 RFC 7231 says HTTP applications may use.
|
||||
.SH 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(), \fIcurl_getdate(3)\fP will return -1 in this case.
