Chris,
CF has consistently maintained adherence to the UDUNITS definition for
the reference time string, and that is different from ISO. (See CF
Section 4.4
<http://cfconventions.org/cf-conventions/v1.6.0/cf-conventions.html#time-coordinate>)
As stated at the top of the section, Z is not used in the case of UTC
and there is a space before any time zone offset. Example 4.4 is written
that way specifically to make it clear that single-digit numbers are legal.
Grace and peace,
Jim

I see in teh doc:
Example 4.4. Time axis
double time(time) ;
time:long_name = "time" ;
time:units = "days since 1990-1-1 0:0:0" ;
IIUC, ISO 8601 requires two digits for the time pieces [1], so that
should be:
"days since 1990-1-1 00:00:00"
The parser I use isn't picky about this, but maybe some are?
BTW, as it's an example, we should probably throw a time offset on
there, too:
"days since 1990-1-1 00:00:00Z"
or
"days since 1990-1-1 00:00:00+00:00"
[1] at least according to wikipedia:
