I'm a little stuck... Click here to teach me more about this clue!

'how long it will' is the definition.
I know nothing about this answer so I can't tell whether this works.

'obligation to overwhelm spirit' is the wordplay.
'obligation' becomes 'tie' (I've seen this before).
'to overwhelm' means one lot of letters goes inside another.
'spirit' becomes 'mescal' (I am not sure about this - if you are sure you should believe this answer much more).
'tie' enclosing 'mescal' is 'TIMESCALE'.

'take' is the link.
