Not the best moment to sort things out (6-5)

I believe the answer is:

second-class

'not the best' is the definition.

'moment to sort things out' is the wordplay.
'moment' becomes 'second' (second moment is a kind of moment).
'to sort things out' becomes 'class' (as in to class or classify things).
'second'+'class'='SECOND-CLASS'

(Other definitions for second-class that I've seen before include "Not of the top group" , "B-rated" .)

I've seen this clue in The Globe and Mail.
