Dave,

I'm working on it.

Unfortunately, I've been sidetracked by a need to revamp the UDUNITS continuous-
integration pipeline.

> The following problem in utCalendar was reported for Udunits versions
> 2.1.19 and 2.1.20.  The function outputs 59 minutes, 60.000 seconds, etc.
> when I expect an even hour result at 0 minutes 0 seconds.  Udunits-1 gave
> the expected results.
> 
> See attached short test program.  Note that I am using the Udunits-1 API so
> that the identical program may be tested with either Udunits-1 or Udunits-2.
> 
> Can you please fix this problem so that Udunits-2 will always round off to
> keep seconds in the 0-59.999 range?  Thank you.
