[CF-metadata] nitpick in time axes example

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:
https://en.wikipedia.org/wiki/ISO_8601#Times
