A potted version after mid-January is certainly not antiquated (8)

'certainly not antiquated' is the definition.
I know nothing about this answer so I cannot tell whether it can be defined by this definition.

'a potted version after mid-january' is the wordplay.
'version' indicates an anagram.
'after' is a charade indicator (letters next to each other).
'mid' says to take the centre (mid- can mean the middle of something).
The middle of 'january' is 'u'.
'a'+'potted'='apotted'
'apotted' is an anagram of 'ptodate'.
'ptodate' put after 'u' is 'UPTODATE'.

'is' is the link.

Can you help me to learn more?
