This has been a test of the emergency broadcast system

On Sunday morning, we were awakened by a guy driving around the neighborhood announcing something over a loudspeaker. Obviously, we had no idea what it was, although the thought occurred to us that it might be someone running for office. We assumed that we would have heard from the US Embassy if it was anything dangerous, so we rolled over and went back to sleep. Sunday was also the end of daylight saving time in Serbia, as in the US. We didn't know if it would change on the same day, but when we got up we checked our clocks against the TV, and they were off by one hour. Our guess is that the loudspeaker was a public service announcement to remind everyone to set their clocks back. I wonder who offers such a service. Given that we're living in a former Communist country, it's almost certain to be a government employee, but that doesn't stop us speculating. My favorite theory is that there's some guy in the neighborhood who always forgets to change his clock, and that the man with the loudspeaker was his boss. "Please be aware that daylight saving time is over, and you should set your clocks back an hour. Boris Jovanovic, this means you."
