This mod is part of The Vanilla Experience.
GUI Clock is a minimalistic client-side mod which shows the time in the GUI on the screen when a clock is in the inventory. It can show in-game time or real time, and can be in the 24 hour format or with AM/PM. It can also show the world's age in days below the time. Instead of showing the time in numbers it's also possible to display the clock icon on the screen instead, can be enabled in the config.

By default the clock will automatically be lowered when a potion effect is active.
