When trying to write the date 1/1/1900 to an xlsx file (using the standard date format of 1900-01-01), the "Microsoft Excel (xlsx)" driver throws an error (ConvError: Output Data (7): Invalid date value encountered - earliest date supported is 12/30/1899 error in field: Field1 record number: 2) and outputs a blank instead of the correct 1/1/1900. If I switch to the "Microsoft Excel Legacy (xlsx)", then it correctly outputs as 1/1/1900 and there are no conversion errors. Is there any chance that the "Microsoft Excel (xlsx)" driver can be fixed so that it outputs 1/1/1900 just like the legacy driver? I've attached a simple example. Thanks for any feedback
