lunchtime

I'm a little stuck... Click here to teach me more about this clue!

'midday meal is taken' is the definition.
I can't tell whether this defines the answer.

'left the cumin out' is the wordplay.
'left' becomes 'l' (common abbreviation).
'out' indicates an anagram (out can mean wrong or inaccurate).
'the'+'cumin'='thecumin'
'thecumin' is an anagram of 'unchtime'.
'l'+'unchtime'='LUNCHTIME'

'when' is the link.

Can you help me to learn more?

(Other definitions for lunchtime that I've seen before include "Midday period for eating" , "free period?" , "When to take a short break" , "One possibly" , "Maybe one" .)
