On https://caniuse.com/#feat=input-datetime there is no detailed information regarding the step property of the input field with type datetime-local and time.

Motivation

It would be great if all browsers would support the step property of the input field with type datetime-local and time.

This would be especially helpful on mobile platforms where browsers use the beautiful native widgets of the operating system. We could implement reservation systems by just using these native widgets without having to use any JavaScript widget library.

If you book a table in a restaurant, a flight, a vehicle, a room, etc. you don’t define the minute exactly. It's almost always just the hour you have to provide or the granularity is 15 minutes or 30 minutes.
