[time-nuts] Absolute time accuracy pre-Cesium?

[Francis Grosz]

Bob,

     Physicists are still debating whether time is continuous or granular.
 One current theory of granularity uses the Planck Time, the time
required for a photon traveling at c, the speed of light in a vacuum,
to travel a Planck Length.  This turns out to be 5.39x10^-44 seconds.
 This is small enough that, for the moment at least, even Time Nuts
can treat time as continuous.

 I have been pondering something somewhat related to all of this.
We know that the smallest unit of a substance is a molecule.? The smallest
unit of
charge is maybe an electron.? So what could one imagine the smallest unit
of time to
be?? Is time digital in the nanoscale, or is it always an analog
measurement?? Or,
more fundamentally, is is just a concept rather than a reality?
