Well, this is kinda stupid, but it still took me too much time to figure it out.

I installed Windows 10 and activated the “use small taskbar buttons” checkbox in the TaskBar properties. Then I changed the taskbar location to be left, going from the top left corner of my screen to the bottom left corner.

My problem was that the clock only showed the time but not the date:

Some research (in the wrong places) revealed that it had to do with the “use small taskbar buttons” setting. The problem is that I want small taskbar buttons AND see time & date.

And here comes the stupid part:

As soon as you switch to small taskbar buttons, the taskbar is no longer wide enough to show the date and therefore just omits it. The solution is really simple:

1. Right-click the TaskBar and make sure that “Lock all taskbars” is UNchecked
2. Drag the right edge of the taskbar just to make it slightly wider
3. *PLOP* the date shows up.
4. (Right-click the TaskBar and activate “Lock all taskbars”)

I hope someone in the world wide web can benefit from this post and save some minutes, hours, days or at least some nerves.  🙂
