'wasted time' is the definition.
(I've seen this before)

'the whole lot faded out' is the wordplay.
'the whole lot' becomes 'all' (I've seen this in another clue).
'faded' becomes 'died' (I've seen this before).
'out' indicates putting letters inside.
'all' put inside 'died' is 'DALLIED'.

'while' is the link.
This may not be right. It may belong to another bit of the clue.

Can you help me to learn more?
