Examples of ucar.nc2.units.DateRange

ucar.nc2.units.DateRange
Implements a range of dates, using DateType and/or TimeDuration. You can use a DateType = "present" and a time duration to specify "real time" intervals, eg "last 3 days" uses endDate = "present" and duration = "3 days". @author john caron
