Knowledge about official U.S local time Quito (Ecuador)

Time zones are a compromise, relaxing the complex geographic dependence while still allowing local time to approximate the mean solar time
There has been a general trend to set the boundaries of time zones west of their designated meridians in order to create a permanent daylight saving time effect
The increase in worldwide communication has further increased the need for interacting parties to communicate mutually comprehensible time references to one another
Thus, the advance of technology has both forced (rail transport) and enabled (modern timepieces) the development of arbitrary official "time."
Time zones are based on Greenwich Mean Time (GMT), the mean solar time at longitude 0° (the Prime Meridian).
The definition of GMT was recently changed – it was previously the same as UT1, a mean solar time calculated directly from the rotation of the Earth.
As the rate of rotation of the Earth is not constant, the time derived from atomic clocks was adjusted to closely match UT1.
In January 1972, however, the length of the second in both Greenwich Mean Time and atomic time was equalised.
The readings of participating atomic clocks are averaged out to give a uniform time scale.
Because of the secular (long term) slowing down of the Earth's rotation leap seconds are periodically inserted into Greenwich Mean Time to make it approximate to UT1.
Because of the method of calculation this new time system is also called Coordinated Universal Time (UTC).
Leap seconds are inserted to keep UTC within 0.9 seconds of UT1.
In this way, local times (Quito) continue to correspond approximately to mean solar time, while the effects of variations in Earth's rotation rate are confined to simple step changes that can be more easily applied to the uniform time scale (International Atomic Time or TAI).
All local times differ from TAI by an integral number of seconds.
With the implementation of UTC, nations began to use it in the definition of their time zones.
As of 2005, most but not all nations had altered the definition of local time in this way.
In England, this involved redefining Greenwich Mean Time to make it the same as UTC.
British Summer Time (BST) is still one hour in advance of Greenwich Mean Time and is therefore also one hour in advance of Coordinated Universal Time.
Thus Greenwich Mean Time is the local time at the Royal Observatory, Greenwich between 0100 hours GMT on the last Sunday in October and 0100 hours GMT on the last Sunday in March.
