Hi Alan,

Getting back to the present issue, example 29 has some pages where the
time range is specified exactly, and that may be all you need to get
the ticks at the exact time intervals that you want. However, if that
doesn't work I suggest you give us a complete but simple test case
(say a subset of example 29 in the language you are most comfortable
with) that demonstrates time format functionality that you think needs
improving. We are open to good suggestions here because a lot of the
PLplot time API is (relatively) new to us as well.
I've attached a small test case for my issue. The time range is 10^8
seconds which corresponds to ~3.2 years so I expect years to be used as
time unit and that xticks are located on new year, i.e., Jan 01 00:00.
With plplot 5.9.6 I get xticks 31 06:00, 31 12:00, and 31 18:00.
Thanks,
Peter
