Wild bear in wood's time for a snack (3,5)
I believe the answer is:
tea break
'for a snack' is the definition.
(tea break is a kind of snack)
'wild bear in wood's' is the wordplay.
'wild' indicates an anagram.
'in' is an insertion indicator.
'wood' becomes 'teak' (teak is a kind of wood).
'bear' is an anagram of 'abre'.
'abre' inserted inside 'teak' is 'TEA-BREAK'.
'time' is the link.
(Other definitions for tea break that I've seen before include "elevenses" , "Temporary suspension of business, morning and afternoon" , "brief rest?" , "Short rest during work" , "Respite and a cuppa" .)
