Ploticus 2.30 date arithmetic package has a bug whereby day-of-week
calculation is wrong. This causes plots that use omitweekends to omit the
wrong days of the week. This was an undesired side-effect of some work I
did this past summer on the date arithmetic package.. I had changed the
base julian date to 1/1/1970 (from 1/1/1977) but it turns out there were
hidden dependencies on the fact that 1/1/1977 was a saturday.
Thanks to the astute users who alerted me to this issue.
The fixed dates.c is available here:
place it in your src directory and do a make clean; make
Pls let me know of any further suspicious behavior noted, especially
related to day of the week!
Because of this and the earlier bug I will try to get a 2.31 out soon.
Just a week or two ago the person who did the AIX ports wanted to
know if 2.30 was "stable".. I said yes and then look what bubbled to the
surface. Ain't it always the way..
