PDT - Pacific Daylight Time
North American time zones:
PDT - Pacific Daylight Time
Time zone offset: UTC - 7 hours
PDT is 7 hours behind of Coordinated Universal Time (UTC)
Note that PDT is a daylight saving time/summer time zone. It is generally only used during the summer in the places listed below, during the winter PST is used instead

Time zone abbreviations: PDT, HAP
Full name is Pacific Daylight Time
HAP - Heure Avancée du Pacifique (French)
Email time zone indicator: -0700
An email sent from someone in the PDT time zone will have the time zone listed as "-0700" in the headers of the email. (However, "-0700" does not have to be in PDT, as other time zones could have the same UTC offset).

For actual dates DST might be observed, look at the examples below
