Minecraft Clock lets you track Minecraft in-game time whether it's nighttime. So, you will never lose the exact time while mining underground.

To use this effectively,
1. Standing on the sea level (y coordinates should be 63)
2. There are 2 ways to start the timer
- Press up button when the last pixel of the sun disappears
- Press down button when the first pixel of the sun appears

On the screen, you will see
1. Minecraft Time in hour:minute
2. Status (DUSK, DAYTIME, DAWN, NIGHTTIME)
3. Time in ticks (24000 ticks = 1 day)

The clock updates every 5 seconds (100 ticks)

Gain as many diamonds as you can by pressing up/down button! As soon as you have enough diamonds, visit the shop by pressing middle button and use your diamonds to buy DPC (Diamond per click) to gain diamonds even quicker!

This is a mini version of Diamond Clicker (Android).
