I think this is a good idea.

I would let it be used for datetime coordinate variables (what is argument against that?)

I would not restrict to Gregorian calendar - let it apply to whatever calendar is being used.

Dear All:

Here's the modified proposal for the datetime_iso8601 standard name:

standard_name: datetime_iso8601

Units: N/A

String representing date-time information according to the ISO
8601:2004(E) standard. Variables with this standard name cannot serve
as coordinate variables. Date-time information is in the Gregorian
calendar. For dates preceding the Gregorian calendar the date-time
information is in the proleptic Gregorian calendar. Possible date-time
string forms are:

<datetime> = <date> "T" <time> <timezone> ;

<date> = YYYY "-" MM "-" DD | YYYY "-" DDD ;

<time> = hh | hh ":" mm | hh ":" mm ":" ss | hh ":" mm ":" ss "." S
       | hh ":" mm ":" ss "," S ;

<timezone> = "" | "Z" | "+" hh | "+" hh ":" mm | "-" hh | "-" hh ":" mm

Where:

* "YYYY" is a four-digit year (0000-9999).

* "MM" is a two-digit month of the year (01-12).

* "DD" is a two-digit day of the month (01-31).

* "DDD" is a three-digit ordinal day of the year (001-366).

* "hh" is a two-digit hour (00-23).

* "mm" is a two-digit minute (00-59)

* "ss" is a two-digit second (00-59).

* "S" is one or more digits representing a decimal fraction of the
  second.

* The value of any designator when not specified is zero.

* If <timezone> is ommitted the default value is "Z".
