[gradsusr] parsing time-units

[afzaalkarori]

  Dear GrADS Users!
I am running opengrads v2.0.1.oga1 on windows xp PC. I need to open an NC file (->sdfopen filename.nc) but gives following error
-> Scanning self-describing file:  D:\E\data\sst\HadOIBl\sst_HadOIBl_bc_64x128_1949_2001_c020411.nc
gadsdf: Error parsing time_units for SDF file.
The ncdump yielded following header information about file 
netcdf sst_HadOIBl_bc_64x128_1949_2001_c020411 {
