Even with the hint
time:units = "seconds since 2009-01-01" ;
it's hard for humans to understand the data values
time = 7776000, 15552000 ;
To see such times in a more familiar form, use the "-t" option:
$ ncdump -c -t mslp.nc
netcdf mslp {
dimensions:
lat = 6 ;
lon = 4 ;
time = UNLIMITED ; // (2 currently)
variables:
float lat(lat) ;
lat:units = "degrees_north" ;
float lon(lon) ;
lon:units = "degrees_east" ;
double time(time) ;
time:units = "seconds since 2009-01-01" ;
float pr(time, lat, lon) ;
pr:standard_name = "air_pressure_at_sea_level" ;
pr:units = "hPa" ;
// global attributes:
:title = "example for workshop" ;
data:
lat = 25, 30, 35, 40, 45, 50 ;
lon = -125, -110, -95, -80 ;
time = "2009-04-01", "2009-06-30" ;
