Today I learned: What Time Do You Have?

The world didn't agree on a singular reference for time until 1880 when the establishment of strict railway schedules mandated it. Instead of asking someone "What time is it," the question “What time do you have?” was more common, since the expectation was that everyone’s watch would have a different one. Clocks and watches at the time were used like egg timers. They gave you a sense of when you had to be somewhere, but there was zero expectation that they would all reflect a single time.
