  -----------
  Add expression functions for handling date/time:

    - year,month,day,hour,minute,second extraction
    - new QgsInterval objects - handles time amounts
    - age() function returns the difference between two  datetimes
    - $now returns the current date and time
    - support for datetime - interval = new datetime
    - tointerval, todate, totime functions
    - tests ;)
