time bounds

[<Mark.Collier@xxxxxxxx>]

Hi

The following descriptor file works o.k., however, it assumes that each
month is of equal size. Is there some way of getting ferret to use the
time bounds information used in the individual files? These separate
files have different time values and upper and lower limits. This would
enable more accurate analysis/plots.

Thanks,
Mark.
