The clock is already very customizable and this is the closest to my liking, screen:

But I will appreciate an option to use dashes in stead of slashes, example:
02:00 10/3/202002:00 10-3-2020Also, I would prefer 10-03-2020 in stead of 10-3-2020.
Of course this is cosmetic and insignificant but I suppose that such new options would be easy to be implemented.
Hi, I'm surprised no one has requested this before. I've been expecting it for since I released the first version 馃槃
I'll add this to the backlog 馃憤

Thank you for the quick response and for adding this to your to do list. I suppose you will also keep slash option so that the users who prefer slashes won't be disappointed. I really prefer dashes but I suppose that if nightTab used dashes I would have requested slashes.
Feature is on master. It will be released in the next update.

Feature is now on live
