I was playing on a server to test a lot of things, one of those is can minecraft read numbers over 2147483647 or the 32 bit integer limit of minecraft or the max int value in minecraft, surprisingly, minecraft doesn't care for values over 2147483647 if its a day value, i dont know anything else that will work with the over 2147483647 value, as shown in the picture the number is more than the 32 bit int limit of (2147483647).

Note: comment if this is a bug, oversight or intentional feature, and find the "Day" value in the F3 screen provided, and this was done a multiplayer server

How to reproduce
1. Create a command block that adds 2147483647 days to the main time
2. Wait until the day counter goes over 2147483647
 The game doesn't do anything about it, not crash or a system error.
