Quantum time is shown to be the time it takes for an elementary particle to absorb an SEQ quantum of space. It is also the time it takes for an small energy quantum, or SEQ, to complete one radial frame advance. This unit of time, associated with the observable universe and matter, is not constant , but increases with expansion.
There is also a frame advance time associated with the whole universe, a much smaller duration of time. This unit of time decreases with expansion.
The ratio of the two levels of time increases at the same rate as the whole universe increases, cancelling the rapid acceleration of the whole, so that we experience a constant expansion rate. This is why we are moving at 2c.
Interestingly, our quantum time equation, when given the mass of the electron, matches a very slightly modified equation for the "chronon" of Piero Caldirola, for the classical electron. The chronon, despite its elaborate construction, appears to be the time it takes for a point, traveling at the speed of light, to transverse the Compton radius of the electron. It matches our frame advance and quantum absorption times.
We go on to show that the quantum time value of any elementary particle can be calculated from the time-energy uncertainty relation. That also means that each particle has a slightly different duration for a unit of quantum time.
We can connect the quantum of space, the elementary particle, quantum time, and quantum gravity, when we state that quantum time is the time it takes for a particle of matter to absorb a quantum of energy.
