It's the number of degrees that the points must remain closed to allow the flux to build up to a sufficient level in the HT coil in a battery powered ignition system.

Or are you talking dwell period? the amount of time/degrees the inlet port is clear of piston? as you stated 30 degrees I suspect that may be what you mean?

this also crossed my mind when i saw this post,
dwell in terms of inlet timing is the amount of time that a port is fully open and unobstructed,
