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.
Nautical time zones are an ideal form of the terrestrial time zone system. Under the system, a time change of one hour is required for each change of longitude by 15Â°. The 15Â° gore that is offset from GMT or UT1 (not UTC) by twelve hours is bisected by the nautical date line into two 7.5Â° gores that differ from GMT by Â±12 hours.
