Castlegate IT WP CMB UK date fields
Adds to the Custom Meta Boxes WP plugin by Human Made two new date fields supporting UK dates. Define a field as a UK date using the type 'UK_date', or a full timestamp using UK_datetime. Dates are stored as UNIX timestamps - use strtotime() in the front end.
Flexible date formats are due to be implemented in a future release of CMB, so this should only be a stopgap.
Requires the Human Made Custom Meta Boxes plugin, natch.
