There Are No Gnu C Library Functions Specifically Oriented Toward Dealing With Elapsed Times, But The Calendar Time, Processor Time, And Alarm And Sleeping Functions Have A Lot To Do With Them.

And gives the number of seconds and microseconds since the epoch (see time (2)). The gettimeofday () function obtains the current time, expressed as seconds and microseconds since 00:00:00 coordinated universal time (utc), january 1, 1970, and stores it in the timeval structure pointed to by tp.
