Why this Sunday has 25 hours (and your phone shows 1:30 twice)

This Sunday lasts 25 hours, and your phone shows 1:30 twice.

Inside, your phone counts time as one number: seconds since 1970. It never jumps. Clock time is that number put through a rule. On 25 October at 2 a.m. the UK rule steps back an hour, so the same label comes round again 3,600 seconds later. The day holds 90,000 seconds, not 86,400.

Send it to whoever always asks if they get an extra hour in bed.
