Because the original stream is not closed, it'll fill up and then 100% packet loss follows.

A simple time change -- as shown below -- is enough to trigger the hard error

import subprocess
import time

shift = 0

print(f"Shifting time by {shift} seconds")
print("Current", time.time())
replacement = int(time.time()) + shift

expected = time.time() + 10
subprocess.check_call(["date"])
subprocess.check_call(["date", "-s", f"@{replacement}"])
