This page documents the changes from the last stable Minecraft release (currently 1.3.1) to the current pre-release (or weekly release).
Time Update (0x4)
Server to Client
Time is based on ticks, where 20 ticks happen every second. There are 24000 ticks in a day, making Minecraft days exactly 20 minutes long.
The time of day is based on the timestamp modulo 24000. 0 is sunrise, 6000 is noon, 12000 is sunset, and 18000 is midnight.
The default SMP server increments both by 20 every second.
The 'Time' is the Age of the world. It is not changing on server commands and will increased by 20 every second.
