Constant datafusion_expr::TIMEZONE_WILDCARD

pub const TIMEZONE_WILDCARD: &str = "+TZ";

Constant that is used as a placeholder for any valid timezone. This is used where a function can accept a timestamp type with any valid timezone, it exists to avoid the need to enumerate all possible timezones. See TypeSignature for more details.

Type coercion always ensures that functions will be executed using timestamp arrays that have a valid time zone. Functions must never return results with this timezone.
