Yes. https://en.wikipedia.org/wiki/Sandford_Fleming ( https://www.smithsonianmag.com/smithsonian-institution/sandf... )

> He promoted worldwide standard time zones, a prime meridian, and use of the 24-hour clock as key elements to communicating the accurate time, all of which influenced the creation of Coordinated Universal Time.

The one bit where this would be problematic would be "what day is it?" When does today become tomorrow?

There are a lot of systems that we've built that depend on that distinction. Things like business days and running end of day so that everything that happens on March 2nd is logged as March 2nd. I've encountered fun with Black Friday sales where the store is open over the midnight boundary and the backend system really wants today to be today rather than yesterday (sometimes this has involved unplugging a register from the network so that it doesn't run end of day, running EOD on the store systems, and then plugging the register back in after it completes and then running a reconciliation.).

Other than that particular mess of banks and businesses... yea, running everything on UTC would be something nice in today's world.

This is also kind of what happens in China (with a complicated history). https://github.com/eggert/tz/blob/main/asia#L272

Aside on the "changing clocks" and realizing my flexible schedule privilege at a company I worked at I switched my schedule from 8-4 to 9-5 with the change in daylight savings so that I maintained a consistent "this is the hour I wake up".

British Columbia to end time changes, adopt year-round daylight time
