I want to find the lap time in minutes and seconds without having to fill
inn
the whole string tt:mm:ss. That is very time consuming when all I want is
to
display the difference between 16:43 and 25:16. Now I have to write
0:16:43
and 0:25:16. I hope to be able to write 16,43 and 25,16 (or 16.43 and
25.16).
Any suggestions?
Many thanks in advance.
