How can I use 2-digit year value in MySQL DATEDIFF() function?

We can use 2-digit year value either in single date expression or in both date expressions used as argument/s in MySQL DATEDIFF() function.

For example, the query below is using 2-digit year value in first date expression and other is having 4-digit year value.

mysql> Select DATEDIFF('18-10-22','2017-10-22');
+-----------------------------------+
| DATEDIFF('18-10-22','2017-10-22') |
+-----------------------------------+
|                               365 |
+-----------------------------------+
1 row in set (0.00 sec)

And the query below is using 2-digit year value in both date expressions.

mysql> Select DATEDIFF('18-10-22','17-10-22');
+---------------------------------+
| DATEDIFF('18-10-22','17-10-22') |
+---------------------------------+
|                             365 |
+---------------------------------+
1 row in set (0.00 sec)
