Cloud movement is jittery when the world's gametime value is large

The Bug

Cloud movement is jittery due to floating point precision errors when the world's gametime value is large.

Steps to Reproduce

There are multiple ways to reproduce this issue (you only need to do one).

Method 1 Steps:

1. Load a world that has been played for a long time (probably at least a few real-life days; it doesn’t have to be all in one session)

2. (Optional) If commands are enabled, run /time query gametime. If the result is a large value, such as 10,000,000 or greater, this effect should be easy to see. If the result is not a large value, the world may not have been played for long enough to see this issue, and you may want to try method 2

3. Observe how the clouds move

→ ❌ The clouds' movement is jittery

Method 2 Steps:

1. Load or create a superflat world with “The Void” preset

2. Execute the following command:

   /tick sprint 10000000

3. Fall into the void and die (this makes the sprinting tick rate run much faster)

4. Wait until the sprint finishes

5. Observe how the clouds move

→ ❌ The clouds' movement is jittery
