About GMT - Greenwich Mean Time

GMT, or Greenwich Mean Time, is the zero when it comes to time zones – they are all counted from the zero meridian that runs through the village of Greenwich.

Countries:

While both the UK and Portugal are officially on GMT you need to pay attention to whether they are actually observing it or are using their own. Britain in the summer for example use British Summer Time – which is different than GMT.

Common cities using GMT:

London, Lisbon, Dublin, Edinburgh

Daylight Saving Time and summer time:

GMT does not observe DST as it is the zero hour time zone – it never changes.



About PST - Pacific Standard Time

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).

Where it is observed:

Most of the Western US and Canada are following Pacific Standard Time.

DST and summer 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.
