Changing dimension values?

[strandwg@xxxxxxxxxxxxx (Gary Strand)]

This is probably a stupid question, but is there an easier way than using nc-
dump to change a dimension's values? Say I want to change time from seconds to
days - just divide every value appropriately. However, I've got quite a lot of
data to go through and a painless method would be very nice.

Thanks for any advice/suggestions.
