splitting up long number

[iFunKtion]

Hi there,

I have some timecodes in the format:

144345.20

how can convert this to a normal timecode that can then be used for calculating time?

To clarify what this is, it is not seconds, it is hhmmss all bunched together, so you have first two digits are the hours the next two minutes and the last four are seconds and milliseconds. That's an awful lot a wheel reinvention.
