I did some more work on "nice numbers" on logarithmic scales about a
year ago, but I need to go back and finish it.

A more systematic approach to a related (but not identical) problem is
discussed in

and implemented in -mylabels- from SSC.

For your time scales, consider different formats for the time variable and also

P.S. I didn't know (or had forgotten) about Rense Corten's blog. He
comments that Statalist "is so busy that it is close to worthless if
you are not looking for something specific".
