Describe the bug
On Ubuntu, it's possible to input more than 2 digits when trying to input a time. The behavior is different than the one in Windows, where the time gets automatically edited to the next meaningfull integer based on last input.

To Reproduce

1. Create a time picker by writing
   DateTime time = new DateTime(timeComposite, SWT.TIME | SWT.SHORT | SWT.BORDER | SWT.CENTER);
2. Interact with it by typing numbers that would result in non-valid hours or minutes, which are shown nevertheless.

Expected behavior
Scenario: 3:00 AM is set.
Try and edit the hours by typing 31. The hours should change to a 1, since 31 would not be valid.
If 1 is pressed again, the hours should change to 11.
If 1 is pressed again, the hours should change to 1, again.

Screenshots

Environment:

• Select the platforms on which the behavior is seen.
  [] All OS
  [ ] Windows
  [x] Linux
  [ ] macOS (can't verify)

• Additional OS info (e.g. OS version, Linux Desktop, etc)
  Ubuntu 20.04 running in a VM.

• JRE/JDK version
  Temurin jdk-17.0.2+8.

Version since
Always been a problem AFAIK.

Workaround (or) Additional context
There are no possible workarounds, since the text that's displayed while in editor mode is inside an incapsulated variable of DateTime.java.

A possible solution may be to make the method "onNumberKeyInput" aware of what's been edited and hence set constraints.
