A method that measures the phase of a damped LC circuit oscillatory transient 
triggered by the event to be timestamped:

A dual of the circuit is readily devised using a CMOS gate plus an open drain 
(or equivalent) gate output for damping/quenching.
However the ADC employed needs to be able to capture a sample burst at a 
relatively high sample rate.
