### Describe the bug For times before the unix epoch (1970-01-01T00:00:00) times at the boundary are incorrectly put into the previous time bin. ### To Reproduce In datafusion-cli: ``` > SELECT date_bin(INTERVAL '30 second', '1969-12-31T19:00:00') as t; +---------------------+ | t | +---------------------+ | 1969-12-31T18:59:30 | +---------------------+ 1 row(s) fetched. Elapsed 0.002 seconds. > SELECT date_bin(INTERVAL '30 second', '1969-12-31T19:00:30') as t; +---------------------+ | t | +---------------------+ | 1969-12-31T19:00:00 | +---------------------+ 1 row(s) fetched. Elapsed 0.001 seconds. ``` ### Expected behavior A time at the date_bin boundary to be in the correct bin: ``` > SELECT date_bin(INTERVAL '30 second', '1969-12-31T19:00:00') as t; +---------------------+ | t | +---------------------+ | 1969-12-31T19:00:00 | +---------------------+ 1 row(s) fetched. Elapsed 0.002 seconds. > SELECT date_bin(INTERVAL '30 second', '1969-12-31T19:00:30') as t; +---------------------+ | t | +---------------------+ | 1969-12-31T19:00:30 | +---------------------+ 1 row(s) fetched. Elapsed 0.001 seconds. ``` ### Additional context _No response_ -- This is an automated message from the Apache Git Service.
