Learned people refuse to waste time visiting this writer (8)

I believe the answer is:
literati
'learned people' is the definition.
(I've seen this before)
'time visiting this writer' is the wordplay.
'time' becomes 'liter' (I can't explain this - if you can you should give a lot more credence to this answer).
'visiting' becomes 'at'.
'this writer' becomes 'I' (the person writing the crossword).
'liter'+'at'+'i'='LITERATI'
'refuse to waste' acts as a link.
This may not be correct. Some or all of it may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for literati that I've seen before include "Well-read types" , "Well-educated readers" , "group of learned people" , "they devour a lot" , "Bookish types" .)
