SYSML2_ — Library description of Duration of is truncated

The description in clause 9.8.8.2.4 is missing the three words at the end of the sentence.
'its start snapshot.'
The above description in the SysML specification should align with corresponding clause 9.2.12.2.5 in the KerML specification to read as follows:
DurationOf returns the duration of a given Occurrence relative to a given Clock, which is equal to the TimeOf the end snapshot of the Occurrence minus the TimeOf its start snapshot.
