+ * {hour}, {min}, and {sec} are zero-padded to two digits each. The fractional
+ * seconds, which can go up to 9 digits (i.e. up to 1 nanosecond resolution),

+ * is required, though only UTC (as indicated by "Z") is presently supported.

+ * with the time format spec '%Y-%m-%dT%H:%M:%S.%fZ'. Likewise, in Java, one
+ * can use the Joda Time's [`ISODateTimeFormat.dateTime()`](
+ * http://joda-time.sourceforge.net/apidocs/org/joda/time/format/ISODateTimeFormat.html#dateTime())
+ * to obtain a formatter capable of generating timestamps in this format.
