What precedes fast time for tossers? (7,3)

I believe the answer is:

pancake day

I believe this clue is a double definition.

'what precedes fast' is the first definition.
(day before Lent)

'time for tossers?' is the second definition.

(Other definitions for pancake day that I've seen before include "Shrove Tues. (colloq.)" , "Shrove Tuesday" .)

I've seen this clue in The Guardian.
