When recording time & date for an event, we look at whether a device is Touch-screen or not to determine which Time Picker to show. This is to allow Tablets, Smartphones and Computers that have touchscreens to use their built-in input methods to handle inputting time to make the process easier than selecting from the time drop-down, which is designed for keyboard & mouse input.

If you are using a computer with a Mouse and Keyboard, but also has a touchscreen, the result is the time picker being displayed as the standard HTML5 time picker, which looks like this:
Default HTML input type

You will still be able to input time on this and have it record and save as normal.
