CDO

All,

I have HDF5 source files with reference times that include UTC. After some variable and attribute changes to the files using (unintentionally) different versions of CDO, some files retained UTC and some haven't:

:CDI = "Climate Data Interface version 1.6.8 (http://mpimet.mpg.de/cdi)" ;
    double time(time) ;
        time:standard_name = "time" ;
        time:bounds = "time_bnds" ;
        time:units = "seconds since 1970-01-01 00:00:00" ;

:CDO = "Climate Data Operators version 1.9.7.1 (http://mpimet.mpg.de/cdo)" ;
    double time(time) ;
        time:standard_name = "time" ;
        time:bounds = "time_bnds" ;
        time:units = "seconds since 1970-01-01 00:00:00 UTC" ;

We don't use UTC in our reference times and I need to remove it. Our current CDO version 1.9.7.1 doesn't remove the UTC using setreftime:

cdo -setreftime,1970-01-01,00:00:00,seconds

Using setreftime of the older version 1.6.8 removes the UTC, is there a more efficient way to remove it with the current CDO version toolset?

thanks!
