Pacific Standard Time is the time of the Western United States and Canada and is typically abbreviated as PST. It is 8 hours behind GMT. This means that when the clock is noon in London (GMT), it is 4AM in Seattle (PST).
Most of the Western US and Canada are following Pacific Standard Time.
This can be a bit tricky as most states on the US Pacific Coast do apply daylight saving time, calling PST for PDT, or Pacific Daylight Time, instead and sets the clocks in November and March respectively.
This is the standard time of the Eastern US, Canada and parts of the Caribbean. It is in most places observed only in the winter months, from November to March. The origin of EST is the same as for most time zones – it was introduced when the railroad was built across the United States. It is important to note that there is also Eastern Standard Time in Australia, but this is usually called AEST and thus not to be confused with EST.
Most of the Eastern seaboard of the US observe EST, as well as most locations in Eastern Canada although there are a few exceptions. Locations such as New York, Washington, Quebec and Ontario are all on Eastern Standard Time. Also some Caribbean locations such as Jamaica, Haiti and Panama are in this time zone.
It is important to note that with the exception of Panama, Jamaica and a couple of locations in Canada and the US most in this time zone do observe DST and thus switch to EDT in the summer. As always, it is better to look up the actual location than the timezone itself.
