Minutes and seconds form field

Question

I need to format a field in a way that a user will enter 2 numbers separated by a comma (f.e. "20.02"), and the value will be stored as minutes and seconds (MM:SS), then I will need this value to be used in various time calculations.

Hi les2worry,
This kind of data I use quite a lot in a couple of run and walking applications. Depending on the wanted accuracy it can be in expressed in minutes, in seconds or in milliseconds. At input users don't need to give any punctuation character, but just the
digits.
So with the second-accuracy:
      Input 2002 yields:               20:02
      Input 1232002 yields:   123:20:02, with no 24-hrs barrier.
For each accuracy I use two functions: Str_to_sec  and  Sec_to_str.
After input the inputted string is parsed over the hrs/min/sec positions, and eventually converted to seconds (handy for calculations) in the function Str_to_sec,  and with Sec_to_str converted to the wished format, in my case e.g.  20:02. I usually
store the formatted result, because the display possibility is far more frequently used than the value for calculation. Using Str_to_sec of the formatted value gives the number of seconds.
