Solve the following python programming problem given the following code:
@ defer.inlineCallbacks 
def runWithConnection(self, func, * args, **kwargs) : 
    'Wraps the .runInteraction() method on the underlying db_pool.' 
    current_context = LoggingContext.current_context () 
    start_time = (time.time () * 1000) 
    def inner_func(conn, * args, **kwargs) : 
        with LoggingContext ('runWithConnection') as context : 
            sql_scheduling_timer.inc_by (((time.time () * 1000) - start_time)) 
            if self.database_engine.is_connection_closed (conn) : 
                logger.debug ('Reconnecting closed database connection') 
                conn.reconnect () 
current_context.copy_to (context) 
            return func (conn, * args, ** kwargs) 
with PreserveLoggingContext () : 
        result = (yield self._db_pool.runWithConnection (inner_func, * args, ** kwargs)) 
defer.returnValue (start_time) 

    
    

    Fix the buggy line: defer.returnValue (start_time)

#Here is Python program to fix the buggy line: defer.
