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.
