There's a DOS interrupt for this. See
doswrap.e in the Jacques Deschenes Collection.

In Windows, Jesus Consuegra has a program in the Archive
that sets your computer's time. He gets the time
from a special site on the Internet.

You are supposed to use time() to measure
differences in time. I don't guarantee that it will always
start at 0 on all versions of DOS, Windows and Linux.
You can set a variable:  start_time = time()
and then measure the difference from that.
If you want the time of day (to the second),
use Euphoria's date() routine.

There's no problem crossing the midnight boundary,
but you can't (easily) time something that takes
longer than 24 hours.

No. Just set start_time = time() again.
