Yes, I considered that, but the data is suppose to be
monthly from 1 Jan 1948, and there are the correct
*number* of months in the time data, just not the
(as far as I can tell) correct values. :-(
So values in the 1700s does me no good either.
I even considered a byteorder problem (although how
this would happen in NetCDF files is beyond me), but
that just make the problem worst.
Cheers,
David
P.S. This MIGHT make sense if it is the number of seconds
since the demise of the dinosaurs, but this seems a dubious
time unit.
