Description

this should be equal to new Date(0) I believe. Here is what i 've done to make sure I always get a date:

if (typeof result.my_col ==="string"){
              result.my_col=new Date(0);
}
/*instanceof Date can also be used
or to cover only that case something like this:
result.my_col ==="0000-00-00 00:00:00"
but I don't remember if the above was the exact string given
*/

The rest of the timestamps is returned as dates so I wouldn't expect this behavior

Research direction
Look at the MySQL client's date parsing logic, likely in the connection or type casting code. Consider how zero dates are handled, as they are invalid dates in MySQL but often stored as '0000-00-00'. The fix should return a Date object (e.g., new Date(0)) instead of a string. Check the existing code to ensure consistency with other timestamp conversions.
