time, nsec – time in seconds and nanoseconds since epoch|
long time(long *tp)
Both time and nsec return the time since the epoch 00:00:00 GMT,
Jan. 1, 1970. The return value of the former is in seconds and
the latter in nanoseconds. For time, if tp is not zero then *tp
is also set to the answer. |
These functions work by reading /dev/bintime.
