Time zones and jet lag

JFKAmerica/New_York — UTC−4 now; UTC−5 standard time, UTC−4 during daylight saving time

Jet lag, flying SIN → JFK. A 12-hour shift turns day into night: the body clock is as far out as it can be, and it makes little difference which way it adjusts. A common rule of thumb is that it adjusts by roughly one time zone a day, so expect up to a week or more to feel fully normal. Flying the other way, the shift is reversed.
