Build Identifier:

I would like to use MonetDB to parse an ISO timestamp. This operation works with copy into for certain timestamps but doesn't work in the SQL layer.

Reproducible: Always

Steps to Reproduce:

  1. select cast('2015-12-08T00:46:60' as timestamp);
  2. select cast('2015-12-08 00:46:60' as timestamp);

Actual Results:

+----------------------------+
| L1 |
+============================+
| null |
