Experts change dates to absorb pressure (6)
I believe the answer is:
adepts
'experts' is the definition.
(adept is a kind of expert)
'change dates to absorb pressure' is the wordplay.
'change' indicates an anagram.
'to absorb' means one lot of letters goes inside another.
'pressure' becomes 'p' (abbreviation).
'dates' is an anagram of 'adets'.
'adets' enclosing 'p' is 'ADEPTS'.
(Other definitions for adepts that I've seen before include "People with talent" , "Those completely skilled in their work" , "Expert or skilled people" , "Proficient people" , "Virtuosos, hotshots" .)
