The simple answer is yes. While almost all of Alaska is on the Alaska Time Zone (AKST), the Aleutian Islands (part of Alaska) are on the Hawaii–Aleutian Time Zone. The Alaska Time Zone sits at (UTC−09:00), which is about 4 hours ahead of New York.
The Hawaii–Aleutian Time Zone is another hour after AKST time (so 4 hours behind New York). Daylight savings time will throw these differences off a bit, but this should give you a good baseline for understanding the Alaskan time zones in their national relevance.
