Transfer time values

[idefix2]

When timer 1 is started, you save the start time:
Timer1starttime := now; When timer 1 is stopped:

elapsedtime1 := now - timer1starttime; When timer 2 is started, again you save the starttime

timer2starttime := now; When time 2 stops, elapsed time is:

elapsedtime2 := now-timer2starttime; Total elapsed time is

totalelapsedtime := elapsedtime1 + elapsedtime2;
