On some computeres CONSIGNOR is not able to get the correct date and time from windows, then the default year 1899 will be shown.
To fix the problem do the following:
Go to windows control panel. ( Start Menu and Control Panel )
Select "Region and Language"
Select some other region/Country then your own country.
Then select back to your own country.
Close the window and restart Consignor.
The date should now be correct.
