Taustin's digital/analogue suggestion is a good point - if not timely ? Sorry....
From my maternal family side - deep south Irish - I still use the "half" and "quarter of" phrases occasionally, I hardly notice them until the odd person says "when ?".
Certainly I remember my early rural Irish time-keeping being fairly independent of watches of any sort, mainly things like "after dark", "before sunset", "mid-day", and the like, until second-hand watches filtered down. Then it was always very general, the "half 3" for example being more of a guide than any accurate statement.
In sharp contrast to the
" any idea what time the train arrives please ?"
" Oh , around 3.47.."
That's definitely the fault of the digital watch.........
