HUD clock shows on the screen a fairly discreet clock that tells us at all times what time it is to be in the game, although it does not do so in numerical form, but rather a line that is crossed, or by the Sun, during the day, or by the Moon, during the night. This will allow us to know if it is day or night when leaving the mines, to give a simple example.
Once the mod is installed, we can activate or deactivate the clock function as we see fit, as well as we can choose the position of said clock on the screen, which will appear by default in the upper left area of the screen. You can also set the size of the clock.
