When you're turning your clocks back one hour tonight - we return to winter-time, from 3am we move back to 2am - just remember that someone will be spending hours to turn back the dials of his 5,000 clock collection.

Metro (UK) reports that a pensioner, Roy West, 75, will use most of the time tonight and tomorrow to do the job.

He has been collecting clocks for almost 40 years and has covered practically every inch of wall space in his two bedroom flat with them.

He has more than 30 bedside clocks, 60 in his bathroom and hundreds more tucked away in cupboards.

The flat is home to 25 Westminster clocks which chime every 5 minutes – meaning Roy and his 68-year-old wife Pauline should have no excuses for missing an appointment.

He previously left the task to his wife, who would take three days to adjust all the hands.

Roy, from Chandler’s Ford, Hampshire, said: ‘It’s a long job but I don’t mind. I don’t want any of my clocks telling the wrong time.’
