Person with record time's over 90 (2-3)
I believe the answer is:
ex-con
'person with record' is the definition.
I know nothing about this answer so I cannot judge whether it can be defined by this definition.
'time's over 90' is the wordplay.
'time' becomes 'eon' (eon is a kind of time).
'over' means one lot of letters goes inside another.
'90' becomes 'xc' (Roman numerals).
'eon' going around 'xc' is 'EX-CON'.
Can you help me to learn more?
(Other definitions for ex-con that I've seen before include "Former jailbird" , "One now free" , "Old lag" , "She used to serve porridge" , "Former prisoner, in short" .)
