Dreadful confusion in Times supplement (4)

I believe the answer is:

mess

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

'dreadful confusion' is the definition.
'mess' can be an answer for 'confusion' (I've seen this in another clue). I'm not sure about the 'dreadful' bit.

'in times supplement' is the wordplay.
'in' says the answer is hidden in the clue.
'MESS' can be found hidden inside 'times supplement'.

Can you help me to learn more?

(Other definitions for mess that I've seen before include "pickle" , "Where soldiers may eat" , "Dirty or untidy state" , "State of confusion - where servicemen eat" , "Disorderly state" .)

I've seen this clue in The Independent.
