Coordinated Universal Time (UTC)

UTC is a time standard centered around Greenwich Mean Time (GMT). UTC historical data can be formatted as “YYYYMMDD-hh:mm:ss”. Please keep in mind this is based on UTC+0, and as a reference, US/Eastern time is approximately UTC-4 or UTC-5 depending on U.S. Daylight savings.

Please note GMT is unaffected by Daylight savings, and so 09:00:00 will be the same time of day year round regardless of the exchange’s or your local daylight savings observation.
