If you don't happen to have a MIDI spec handy (I think the part about 
standard MIDI files is available on the MMA website) then have a look at 
http://www.borg.com/~jglatt/

Specifically, note the section on "Tempo and Timebase" under 
http://www.borg.com/~jglatt/tech/midifile.htm

This has all the formulas needed to convert musical time (which is used 
by the deltas in most midi files) to real time in msecs, using the 
division of the file (specified in the MThd chunk) and the Tempo meta 
events.
