Subsetting

Dear all,

I need to take a common time range (say 1985-2000) while manipulating many
netcdf files with different time range. I'm just wondering if it is
possible to take a subset of the data along the time dimension by
providing the actual dates rather than the timesteps. For example rather
than doing:

in = addfile("UDEL_1900_2010_v301.nc","r")
  pre = in->precip({1020:1331},:,:)

which requires you know the exact time step representing 198501 and 200012,
I would like to input directly the actual date when doing
pre = in->precip(date_start:date_end},:,:).

Is there a way to do it such that NCL will undertand it?

Thanks.
Almami
