We recommend looking up by location name, not time zone name.

Time zone offset: UTC - 4 hours

AMT is 4 hours behind of Coordinated Universal Time (UTC)

Note that some places observe daylight saving time/summer time during summer, and are therefore using AMST instead in the summer. See below for details.

Time zone abbreviation: AMT

Full name is Amazon Time

Email time zone indicator: -0400

An email sent from someone in the AMT time zone will have the time zone listed as "-0400" in the headers of the email. (However, "-0400" does not have to be in AMT, as other time zones could have the same UTC offset).

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