Yes.  Some perl modules would make that pretty simple.  That's probably
the method I would use.  I do wish both sscreate and sscomp had
equivalent 'nsavetime' reports.

Note that 'nsavetime' is the same as 'savetime', not the same as
'sscreate'.  

The difference shows up if the clocks on the client and server are not
the same.  'savetime' and 'nsavetime' are client based.  'sscreate' and
and 'sscomp' are server based.  To find duration, you want to either
parse and subtract sscomp from sscreate, or parse out the duration from
the savegroup completion.
