Still child a shy DI set off (2,4,3)

I believe the answer is:

to this day

'still' is the definition.
(thesaurus)

'child a shy di set off' is the wordplay.
'child' becomes 'tot' (term for a young child).
'set off' indicates anagramming the letters (letters made to move or set off).
'a'+'shy'+'di'='ashydi'
'ashydi' is an anagram of 'hisday'.
'tot'+'hisday'='TO THIS DAY'

I've seen this clue in The Daily Express.
