But the Drupal dates are an int field.  You'll need to convert the
integer time into the Datetime format and vice versa. See
http://us.php.net/time for information on what Drupal stores.

Hi Earnie
The Date module creates the fields as "datetime"..

From phpMyAdmin
`field_booking_actual_value` datetime DEFAULT NULL,
`field_booking_actual_value2` datetime DEFAULT NULL,

Today I have been looking at the node_save and drupal_execute options for creating nodes programatically.. It doesn't look too difficult (famous last words) so may be a solution to working with the drupal data and creating or updating nodes from our clocking interface..

The MSAccess issue is resolved now by using a feed to import the bookings from a CSV..
