So it must be like this...
showing tenth of a sec
-zeropad(int(time/60% 60), 1) & ":" & zeropad(int(time%60), 2)& ":" & zeropad(int((time*10)%10), 1)
showing hundredth of a sec
-zeropad(int(time/60% 60), 1) & ":" & zeropad(int(time%60), 2)& ":" & zeropad(int((time*100)%100), 2)
showing thousandth of a sec (millisec)
-zeropad(int(time/60% 60), 1) & ":" & zeropad(int(time%60), 2)& ":" & zeropad(int((time*1000)%1000), 3)
...is this correct?
