mktime
[convert time to arithmetic representation]
SYNOPSIS #include <time.h> time_t mktime(struct tm *timp);
DESCRIPTION
mktime
assumes the time at timp
is a local
time, and converts its representation from the traditional representation
defined by struct
tm
into a representation suitable for arithmetic.
localtime is the inverse of mktime.
RETURNS
If the contents of the structure at timp
do not form a valid calendar time representation, the result is -1.
Otherwise, the result is the time, converted to a time_t
value.
COMPLIANCE
ANSI C requires mktime.
mktime requires no supporting OS subroutines.
