Little over a second to divide (6)
I believe the answer is:
bisect
'divide' is the definition.
(I've seen this before)
'little over a second' is the wordplay.
'little' becomes 'bit' (I've seen this in other clues).
'over' indicates putting letters inside.
'a second' becomes 'sec' ('sec' can be a synonym of 'second').
'bit' going around 'sec' is 'BISECT'.
'to' acts as a link.
(Other definitions for bisect that I've seen before include "Divide into two equal parts" , "Cut equally in two" , "Halve (angle)" , "equally split" , "Cut or divide in two" .)
