    CONVERT_TIMEZONE

    Convert timestamp to the specified timezone

    Syntax

    CONVERT_TIMEZONE([sourceTimezone string], destinationTimezone string, timestamp date, timestamp, or string in ISO 8601 format) → timestamp

    • sourceTimezone (optional): The time zone of the timestamp. If you omit this parameter, Dremio assumes that the source time zone is UTC.
    • destinationTimezone: The time zone to convert the timestamp to.
    • timestamp: The timestamp to convert

    Usage Notes

    • The sourceTimezone and destinationTimezone parameters may be timezone_name from sys.timezone_names, timezone_abbrev from sys.timezone_abbrevs, or a UTC time offset such as “+02:00”.

    • If you specify a time zone name instead of time offset, you may get a different answer depending on when you call this function due to daylight saving time.

    • The sourceTimezone and destinationTimezone parameters may be timezone_name from sys.project.timezone_names, timezone_abbrev from sys.project.timezone_abbrevs, or a UTC time offset such as “+02:00”.

    • If you specify a time zone name instead of time offset, you may get a different answer depending on when you call this function due to daylight saving time.
