code: def seconds_left(self):

                      Date(self).datetime).total_seconds())
docs: Remaining part of the year in seconds.
  
          In the first example, only one minute and thirty seconds of the year
          remain:
  
          >>> from hydpy.core.timetools import TOY
          >>> TOY('12_31_23_58_30').seconds_left
          90
  
          The second example shows that the 29th February is generally included:
  
          >>> TOY('2').seconds_left
          28944000
