The odds are that it's almost lunchtime (3,2,3)

'lunchtime' is the definition.
Both the definition and answer are singular nouns.
Perhaps there's an association between them I don't understand?

'the odds are that it's almost' is the wordplay.
'the odds are' becomes 'tento' (I can't justify this - if you can you should believe this answer much more).
'that' becomes 'yon' (archaic term meaning 'that').
'it' becomes 'e' ('e' can mean 'electronic' which is similar to 'IT').
'almost' means to remove the first letter.
'yon'+'e'='yone'
'yone' with its initial letter taken away is 'one'.
'tento'+'one'='TEN-TO-ONE'
