That is the system clock all I did was subtract the system clock for when
the program began to the system clock after the loop. The t1 is the number
of seconds from that date in 1970 so with that you should be able to use the
ctime on the page I sent you to get a printable time. I really think you
need to read the page I sent you .

Got it. Is there a way to apply this to tracking the system clock instead
of the elapsed time of a program?
Have a great day,
Alex
