[mpas-developers] update on date/time manager

[Michael Duda]

Phil,

thanks for the insight on the additional burden in adopting the
full ESMF library. I'd also favor using just the stand-alone ESMF
time manager, even if it does require us to write a bit more of
our own code within the MPAS time manager wrapper.

I'll have a go at adding the ability to set time intervals in
years and months via the ESMF 2.1.1 code. Thanks, again!

Cheers,
Michael

Used to be that ESMF_init also did an MPI_init (with a serial wrapper if you're not building parallel code) - not sure whether that's still the case.  The point is that it will affect code beyond just what you want to use.

It's also one of my pet peeves - frameworks that force you to adopt the whole thing instead of being able to use/adopt in a piecewise manner.
