This Time Zone Calculator converts between different time zones. To determine time zones for various locations, use this page as a reference.

Weather observations around the world including surface, radar, and other observations are always taken with respect to a standard time. It is also known as "Z time" or "Zulu Time". To obtain your local time here in the United States, you need to subtract a certain number of hours from UTC depending on how many time zones you are away from Greenwich England. The table below shows the standard difference from UTC time to local time. The switch to daylight saving time does not affect UTC.

At different times in the past, it has been calculated in different ways, including being calculated from noon ; [1] as a consequence, it cannot be used to specify a particular time unless a context is given. Because of Earth's uneven angular velocity in its elliptical orbit and its axial tilt , noon GMT is rarely the exact moment the Sun crosses the Greenwich Meridian [b] and reaches its highest point in the sky there. This event may occur up to 16 minutes before or after noon GMT, a discrepancy described by the equation of time. Noon GMT is the annual average the arithmetic mean moment of this event, which accounts for the word "mean" in "Greenwich Mean Time". Originally, astronomers considered a GMT day to start at noon, [d] while for almost everyone else it started at midnight. To avoid confusion, the name Universal Time was introduced in to denote GMT as counted from midnight. The term GMT should thus not be used for purposes that require precision.

As the United Kingdom developed into an advanced maritime nation , British mariners kept at least one chronometer on GMT to calculate their longitude from the Greenwich meridian, which was considered to have longitude zero degrees, by a convention adopted in the International Meridian Conference of

Midday in Hawaii will occur at a different time than in Moscow precisely because of the rotation of the Earth, so to make sense of time around the world and to calculate what time is it where, time zones were introduced. This happened in the late nineteenth century when a Scottish-Canadian engineer and inventor Sandford Fleming proposed dividing the Earth into 24 slices of 15 degrees each. However, this does not mean that all countries in the GMT time zone have the same hour. That is, a time zone will cover the same countries vertically, which is why the UK and South Africa observe the same time. Once again, this has to do with the rotation of the Earth: noon is noon from North to South, because the poles do not move; West to East, however, sees a difference as the Earth turns around its own axis.

The Interpretation Act , section 9, provides that whenever an expression of time occurs in any Act, the time referred to shall unless otherwise specifically stated be held to be Greenwich mean time. Russia on the other hand, is divided into 11 time zones, though at one point this was reduced to 9 time zones. As an example, the Eastern Time zone difference from UTC is -4 hours during daylight saving time rather than -5 hours as it is during standard time. Government of Ireland.
