MIDI Clock is a synchronisation method to get the song position follow a
certain master track. When using this the master sends out MIDI Clock
messages (0xf8) at a rate of 24 messages per quarter note. The timing
reference is purely relative to tempo and measure, and does provide
information about transport time expressed in seconds or sample frames.
If the tempo of the music goes up, the rate of MIDI Clock will follow

Though the MIDI Clock is perfectly usefull for synchronising tempo related
things (drum machines, MIDI sequencers, arpeggiators, delays etc.), it won't
help you get your DAWs running in sync.

hope this helps,
