I am executing the following queries:

SELECT * FROM stock_quant WHERE write_date > '2021-06-19 15:12:11' and the Odoo API also returns records that have write_date = '2021-06-19 15:12:11'

I have executed the following query and SELECT * FROM stock_quant WHERE write_date <= '2021-06-19 15:12:11' and the Odoo API doesn not return records that have write_date = '2021-06-19 15:12:11'.

I would expect that for the first query the api will return only records that have write_date greater than '2021-06-19 15:12:11'. And in the second query I expect to get records that have write_date less then or equal to '2021-06-19 15:12:11', but this does not happen.

Could you please let me know why there is such a behaviour?
