Local sunset for WBZ is later than for other stations

[Dan Strassberg]

There is some bizarre FCC rule that allows AM stations to keep IBOC (which
was originally supposed to be shut off at local sunset) on after local
sunset--but not all night. With the end of Daylight Saving Time and until
the end of October (today), Boston FCC sunset is 5:00 PM. IIRC, Boston FCC
sunset is at 4:30 PM in November. It's 5:18 now, and I still hear IBOC hash
from WBZ. Anybody know when it's supposed to go to sleep for the night?
