Jet lag. Jet lag is a mismatch between your body clock and the local time wherever you are. It's caused by rapid travel across time zones. Jet lag is also compounded by the fact that long hours spent on a plane can cause you to sleep too much, or not enough, possibly at the wrong time of day relative to where you departed from.
Eastern vs. Pacific Time. Every place on earth has its own standard time. This is because of the time zone. A time zone is a place on earth where it is properly located between the lines of the longitude. This is also one of the factors why you get jetlagged when travelling from coast to coast. A time zone follows a legally mandated standard time called local time.
