The struct timeval structure represents an elapsed time. It is
declared in `sys/time.h' and has the following members:
long int tv_sec -> This represents the number of whole seconds of
elapsed time.
long int tv_usec -> This is the rest of the elapsed time (a fraction
of a second), represented as the number of microseconds. It is
always less than one million.
------
The struct timespec structure represents an elapsed time. It is
declared in `time.h' and has the following members:
long int tv_sec -> This represents the number of whole seconds of
elapsed time.
long int tv_nsec -> This is the rest of the elapsed time (a fraction
of a second), represented as the number of nanoseconds. It is
always less than one billion.
-----
The gettimeofday() function shall obtain the current time,
expressed as seconds and microseconds since the Epoch, and store
it in the timeval structure pointed to by tp. The resolution of
the system clock is unspecified.
If tzp is not a null pointer, the behavior is unspecified.
