“seconds since 2015-12-31 18:00:00Z” follows the
ISO
8601 standard for time formatting.
https://de.wikipedia.org/wiki/ISO_8601
The CF-Conventions does not provide a mandatory format. Actually, in https://cfconventions.org/Data/cf-conventions/cf-conventions-1.8/cf-conventions.html you can find also an example that follows the
ISO
8601 standard:
Example 5.7. Lambert conformal projection
time:units = “hours since 2004-06-23T22:00:00Z”;
Therefore it is a problem in
CDO
.
Since we start climate simulations generally at 00UTC, this does not harm.
If you really want to start at 18
UTC
, the only work around is to replace the T by a blank in netcdf_io.f90 at about line 1900 and create a new executable.
