What are appropriate functions to do Date and Time comparison?
like:
  Date difference
  Date Comparison?
  Adding 'n' days to current date string value, Removing 'n' month, etc.....
 Where can i find the date integer enconding used in PHP?
 Like i know how it's done in Delphi (as stored as a Double value)
 but in PHP, the date integer how is it encoded?

thanks.
