Android time zone confusion

Question

I'm confused as to why, under Settings -> Date & Time -> Select time zone (uncheck Automatic), Android says Eastern Time is GMT-4:00, when everywhere else, Eastern Time is GMT-5? The reason I ask, is that I'm trying to convert datetime values to the user's current time zone.

Answer 1

Is it from daylight savings time? In November when we no longer "save daylight", we will be GMT-5:00.
