Hi Erik,
We use this already without fractions. For the time definition there is a 
dedicated XSD. Please find it attached.

Subject:        Time Code B

At today’s CESG telecon, it was agreed that in fact the current CCSDS Time 
Code B definition does not require fractional seconds.  More directly, 
YYYY-DDDThh:mm:ss  is fine -- ss.s is not required. 
I will ensure that the SOS book properly calls out YYYY-DDDThh:mm:ss 
format.  Can you please revise the “official” schema?  I believe this is, 
for now at least, in our common type definitions.
As an aside, 301x0b4 is due for 5 year refresh, and may, as a result, have 
some examples added to help clarify the situation.
