Dmitri,

In fact, there are at least 4 categories of timer that you might
be wanting here.

program timer
program clock
command line timer
command line clock

For program timer:
Use select() or usleep() etc.

For program clock, use gettimeofday().

For command line timer, use sleep(1) but that isn't useful for sub-second
timing.

For command line clock, use time(1).

Cheers,
Alan Kennington.
