How would I turn a number in seconds into the normal time format of 0:00:00:000 (hours:minutes:seconds:milliseconds)

So, if the number of seconds was 125 then the time would be
0:02:05
Then show it without the erroneous numbers to make
2:05

Another problem is to show the 0 when the seconds is less than ten.
So, instead of 0:3 show 0:03

Sorry if I have confused any of you. thanks.
