Description:
The TIMESTAMPDIFF function appears to return incorrect values when a negative
number should be returned.
Example:
- For the inputs TIMESTAMPDIFFMONTH("2019-06-30", "2019-03-31") it should
return *-3**,* but it returns *-1*
- For the inputs TIMESTAMPDIFFMONTH("2019-06-30", "2019-05-31") it should
return *-1**,* but it returns *1*
