decode_mime_time

#include "sflmime.h"
Bool
decode_mime_time (const char *mime_string, long *date, long *time)

Synopsis

Takes a MIME date and time string in various formats and converts to a date and time (both long values). Returns TRUE if it could convert the date and time okay, else returns FALSE. Accepts these formats:

Mon Jan 12 12:05:01 1995	ctime format
Monday, 12- Jan-95 12:05:01 GMT	RFC 850
Monday, 12-Jan-1995 12:05:01 GMT	RFC 850 iMatix extension
Mon, 12 Jan 1995 12:05:01 GMT	RFC 1123

The returned date and time are in local time, not GMT.
