Add possibility to use as hours-only timer

[michaelkowalski]

In a project I'm working on we only need something like HH:MM:SS. When we set the timer to 2 days, it was displaying 23:59:59 etc.

I can make a more generic solution if you have some ideas.

It'll be great if this solution were extended to all parts of timer.

Oh, sorry guys! Didn't check responses here. Are you still in need of something like that? If yes, please mention me I'll then get a notification 😅
