GFAS data are 24 hour means. The GRIB to NetCDF converter uses the end of the period which makes it look like there is a 24 hour offset in the data output (e.g. when one requests GFAS data for 2022-01-01/2022-01-03, the data output starts at 2022-01-02 00:00:00 and ends at 2022-01-04 00:00:00). Other users reported this behaviour on our Forum e.g. https://forum.ecmwf.int/t/download-time-series-wrong/8049
