Currently I am not sure what font it uses but it's not the system font. It would be great to use the system font to fit in with other widgets. Second wishlist is if we could configure it. Code is already in Digital Clock widget if it makes it easier.
Can you provide a screenshot? Looks to me like it uses the system font.

Can you point out where in that screenshot the nonstandard font is being used?
On the left in the panel where it says 18.0 C, this font doesn't look the same as the Digital Clock font, which in the screenshot shows the settings and it's set to Default. Not sure if the font is the same but the size and thickness are not.
Oh that. It can't use the system font size because it scales with panel thickness, same as the Digital Clock's text. However the two are supposed to scale their text in the same way and clearly this isn't happening. Can confirm that. Re-titling.
