can anyone point me to some information about time signatures and tempo
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.
