Ten past two (6)

I believe the answer is:
twelve
This clue could be a double definition.
'ten' is the first definition.
The definition and answer can be both quantities as well as being singular nouns.
Maybe they are linked in a way I don't understand?
'past two' is the second definition.
The definition and answer can be both quantities as well as being singular nouns.
Perhaps there's an association between them I don't understand?
Can you help me to learn more?
(Other definitions for twelve that I've seen before include "Number of zodiac signs" , "The midnight hour" , "Six twos" , "six couples" , "Midday" .)
