Pranjal Kole 0da19a81bc replace gettimeofday with clock_gettime
POSIX.1-2008 has marked gettimeofday(2) as obsolete, recommending the
use of clock_gettime(2) instead.

CLOCK_MONOTONIC has been used instead of CLOCK_REALTIME because it is
unaffected by manual changes in the system clock. This makes it better
for our purposes, namely, measuring the difference between two points in
time.

tv_sec has been casted to long in most places since POSIX does not
define the actual type of time_t.
