More precision can be used. See below.

The EPP documents have normative references to RFC 3339 and the XML Schema
specifications. 3339 specifies this syntax for fractions of a second:
time-fraction = ("," / ".") 1*DIGIT
which means at least 1 digit with no upper limit on the number of digits.
The EPP documents use the XML Schema "dateTime" data type. The XML Schema
text for the dateTime data types says this:
"Additional digits can be used to increase the precision of fractional
seconds if desired i.e the format ss.ss... with any number of digits after
the decimal point is supported."
So, it's all there in the normative references and the normative data type
definition.
