Number Formatting: Display Cells As A Number Like "00 41 55.0"

I have two columns of cells that need to be reformatted: B and C. In the B column excel is reading the cells as time (0:41:55.0), I need it to display those cells as a number like this: 00 41 55.0. In column C the cells look like this: 41 : 09 : 47.3. I need the C column cells to look just like the formatted B column cells (41 09 47.3) Also, even though they have the spaces, the numbers should be read by excel as one whole number (i.e. 41 09 47.3 would be used in a calculation as 410947.3)
