Mock data requires US 'iso mdy' format

[Kalsyc]

Currently, the mock data lists the dates in mmddyyyy format. However, upon installing postgresql for windows, it automatically uses the default ddmmyyyy format which causes some problems when importing data.

Although, we can fix it by simply changing the postgresql.conf file and restart the postgresql service, we should follow the live server's way of inserting the dates.

Should we just change the mock data such that it fits the ddmmyyyy format? Or use some standard timestamp format that is easy for mock data to be created too.
