Nor was it easy to get working to the extent it does.  Calendars are a 
major pain in the lower back.

Roughly said, the automatic routines handling time/date tic placement 
are best left to their own devices.  Forcing your own tic interval on 
them may work --- but it's very hard to make any guarantees there.

... and just in case somebody wonders about that: yes, it is necessary. 
  That's what you get for pretending that a month were an equidistant 
tick interval that can be sequenced, miniticked, and so on.  Well, it's 
not, and so all major ticks have to be adjusted to actually fit on the 
scale.

I think the proper patch would involve a routine that works much like 
quantize_time_tics(), but leaves alone the input 'tics'.
