'let's get a move on as this could be the witching' is the definition.
I don't know anything about this answer so I can't tell whether it can be defined by this definition.

'hour for west african country' is the wordplay.
'hour' becomes 'time'.
'for' says to put letters next to each other.
'west african country' becomes 'togo' (I've seen this before).
'time'+'togo'='TIME TO GO'
