Struct DFTimestampWithOffset 

Source 
pub struct DFTimestampWithOffset { /* private fields */ }
Expand description

Defines the extension type logic for the canonical arrow.timestamp_with_offset extension type. This extension type allows associating a different offset for each timestamp in a column.

See DFExtensionType for information on DataFusion’s extension type mechanism. See also TimestampWithOffset for the implementation of arrow-rs, which this type uses internally.
