9.7 `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.
PORTABILITY
ANSI C requires `mktime'.
`mktime' requires no supporting OS subroutines.
