Bruce is right as this is about Longitude and not Time Zones.

Of course if you REALLY want the Easternmost part of the
U.S. you all need to back up from your original thinking
from Attu at 172 Degrees East Meridian and go to
Semisopochnoi Island.  The Easternmost point on which is
Pochnoi Point which is much closer to 179 Degrees East
Meridian.

(a.k.a. Somewhere midway between Kiska and Adak.)
