From AOPA's most recent newsletter:
The Hobbs meter in most airplanes is triggered by a set oil pressure (10 psi) and runs only when the engine does. The Hobbs meter counts the same no matter how fast the engine runs. Tach time, on the other hand, is designed to count accurately only at a certain engine speed, usually a high cruise (i.e. 2500 rpm)
