I is 9 hours ahead of Coordinated Universal Time (UTC)
Time zone abbreviation: I
Full name is India Time Zone
Email time zone indicator: +0900
An email sent from someone in the I time zone will have the time zone listed as "+0900" in the headers of the email. (However, "+0900" does not have to be in I, as other time zones could have the same UTC offset).
Important Note
India’s time zone, known as Indian Standard Time, is five hours and 30 minutes ahead of Coordinated Universal Time (or UTC+5:30). This time zone is not to be confused with a military time zone that is known as the India Time Zone (abbreviated as “I”) , which is UTC+9.
Time zone maps are under development and will be available later
