Entering a time in the post publish settings is not working

[moorscode]

Issue Overview

Currently it is impossible to:

• clear the field
• enter a time that starts with 00
• easily change a time to anything other than: 01, 10, 11 or 12

And it is very hard to change the time, as by default a 1 is entered, but the only accepted characters after that are 0, 1 and 2 to create 10-12.

Steps to Reproduce (for bugs)

For the hours:

1. Enter '1' as the hour to publish a post
2. Try to change it to '8'

For the minutes:

1. Enter 21 as the minutes
2. Try to change it to 31 by just changing the 2 to a 3

Try to use the backspace to change the numbers or clear them.

Sometimes even changing the hours to anything other than a 7 does not work at all.

[ Browser: Chrome, Firefox ]

Possible Solution

Fix it.

Screenshots / Video

I tried to make a recording, but the keypresses are not shown, so backspaces are not pointed out.
