`play` · `0x5B` · **clientbound** (server → client)

Sets how many seconds before the border reaches the player the warning tint starts. The server sends it when the border warning time changes.

Sent by the server, read by the client. Listen for it with `client.on("SetBorderWarningDelay", (data) => …)` on the receiving side.
