Tabloid calls for old timers? (8)
I believe the answer is:
sundials
'old timers?' is the definition.
(I've seen this in another clue)
'tabloid calls' is the wordplay.
'tabloid' becomes 'Sun' (The Sun, UK newspaper).
'calls' becomes 'dials' (I've seen this in another clue).
'sun'+'dials'='SUNDIALS'
'for' is the link.
(Other definitions for sundials that I've seen before include "Daylight timekeepers" , "They tell the time when there's no cloud" .)
