Solve the following python programming problem given the following code:
def test_subscribe_to_time_changes(self) : 
    time_options_manager = TimeSettingsManager () 
    result = { 
        'result' : 'time', 
} 
    def time_change_callback(time, minutes, seconds, origin_station_name) : 
        result ['result'] += (' ' + time) 
time_options_manager.subscribe_to_timechange (time_change_callback) 
    time_options_manager.increment_seconds () 
    self.assertEqual (time_options_manager ['result'], 'time 10:00 10:15') 

    
    

    Fix the buggy line: self.assertEqual (time_options_manager ['result'], 'time 10:00 10:15')

#Here is Python code to fix the buggy line: self.

self.assertEqual (result ['result'], 'time 10:00 10:15')
