char* Ns_HttpTime	(	Ns_DString *	pds,
		time_t *	when
	)

----------------------------------------------------------------------

Ns_Httptime --

Convert a time_t into a time/date format used in HTTP (see RFC 1123). If passed-in time is null, then the current time will be used.

Results: The string time, or NULL if error.

Side effects: None.

----------------------------------------------------------------------

This will most likely break if the locale is not an english one. The format is RFC 1123: "Sun, 06 Nov 1997 09:12:45 GMT"

time_t Ns_ParseHttpTime

(

char *

str

)

----------------------------------------------------------------------

Ns_ParseHttpTime --

Take a time in one of three formats and convert it to a time_t. Formats are: "Thursday, 10-Jun-93 01:29:59 GMT", "Thu, 10 Jan 1993 01:29:59 GMT", or "Wed Jun 9 01:29:59 1993 GMT"

Results: 0 if error, or standard time_t.

Side effects: None.

Find the comma after day-of-week

Thursday, 10-Jun-93 01:29:59 GMT ^ +-- s

Thu, 10 Jan 1993 01:29:59 GMT ^ +-- s

Advance S to the first non-space after the comma which should be the first digit of the day.

Figure out which format it is in. If there is a hyphen, then it must be the first format.

The format is:

Thursday, 10-Jun-93 01:29:59 GMT ^ +--s

The format is:

Thu, 10 Jan 1993 01:29:59 GMT ^ +--s

No commas, so it must be the third, fixed field, format:

Wed Jun 9 01:29:59 1993 GMT

Advance s to the first letter of the month.

If there are any impossible values, then return an error.
