Is it possible to set a timeout on a socket in Twisted?

from twisted.internet import task
from twisted.internet import reactor

datagramRecieved = False
timeout = 1.0 # One second

# UDP code here

def testTimeout():
    global datagramRecieved
    if not datagramRecieved:
        reactor.stop()
    datagramRecieved = False


l = task.LoopingCall(testTimeout)
l.start(timeout) # call every second

# l.stop() will stop the looping calls
reactor.run()

class Protocol(DatagramProtocol):
    def __init__(self, timeout):
        self.timeout = timeout

def datagramReceived(self, datagram):
    self.timeout.cancel()
    # ...

def datagramReceived(self, datagram):
    self.timeout.cancel()
    # ...
