time axis specification

[John C Cartwright <John.C.Cartwright@xxxxxxxx>]

Hello All,

if I have a netcdf file described by the following header:

netcdf example {
dimensions:
        time = UNLIMITED ; // (12 currently)
        lat = 180 ;
        lon = 360 ;
variables:
        int test(time, lat, lon) ;
                test:long_name = "Sample Data" ;
                test:units = "calibrated" ;
        float lat(lat) ;
                lat:units = "degrees_north" ;
        float lon(lon) ;
                lon:units = "degrees_east" ;
        int time(time) ;
                time:units = "days since 1900-01-01" ;

// global attributes:
                :title = "Sample Data" ;
}

I'm trying to represent monthly time slices for January 1986 through 
December 1986. How should I set up my time axis in server/las.xml?

I would have guessed something like:

    <ged_time type="t" units="days">
     <arange start="1986-01-01" step="1" size="12"/>
    </ged_time>

but the actual values in the time dimension are integer days 
representing the first day of each month. Should the units be months in 
order to have a step size of 1?

Thanks!
