//
// Additional Notes: modified/redesigned for use within skOOchie by Mark Slemko 2005
// Version: 2.0
//  -- thanks to Denis for the great starting point
// changes: (There are many - so the code is quite different)
//  - improved display to use css class relations in generated html page
//  - added timezone artifacts (incomplete)
//  - improved calendar selection of days
//  - improved x-platform compatibility (incomplete I'm sure)
//  - added functionality for usage with Safari browser
//  - added drop-down time picking
//  - added 'gestured' next-day time picking
//  - improved date display to be non-ambiguous yyyy mm dd
//

// MS: browser detection... I hate this, but it seems necessary right now...
