Dave Allan (he's Mr. Allan - amazingly, he does not have a PhD)
has published many papers over his long, productive career.  I
might have his paper here on clock ensembles, but I'd need a bigger
hint on where/when/if it might be published in order to find it.

Sam Stein (Dr. Stein) is truly a guru in timescales and his company,
Timing Solutions, is very successful.  Thanks for the pointer to his

One of the most advanced timescale algorithms is the KAS2 which
timing.com has patents on.  There is a paper describing it here:
