The date displayed in the table is in US format and there is no way to change this through the preferences.
Either the date should be in ISO standard form, i.e. yyyy/mm/dd or it should be configurable.

The date format is displayed according to your OS language settings. Adding a config option to the preferences dialog should be possible though.
