Email time zone indicator: +0100

An email sent from someone in the IST time zone will have the time zone listed as "+0100" in the headers of the email. (However, "+0100" does not have to be in IST, as other time zones could have the same UTC offset).

Important Note

The term “IST” is not the legal abbreviation to describe Irish Summer Time but it is commonly used. IST is described as “summer time”, according to Irish law, while Irish Standard Time is described as both “standard time” and “winter time”.
