When testing the SIP protocol on Python 3,
I found that if I did:

env TWISTED_REACTOR=asyncio python -m tox -r -e py36-alldeps-nocov-posix twisted.test.test_sip.RegistrationTests.testRegister

I got:

[FAIL]
Traceback (most recent call last):

twisted.test.test_sip.RegistrationTests.testRegister

It seems that the asyncio reactor's callLater() method
returns a DelayedCall, and the getTime() method on this object is
returning a timestamp that is not relevant to the epoch.

This causes this test to fail.

Start with twisted.test.test_sip.RegistrationTests.testRegister and the asyncio reactor's callLater() and DelayedCall behavior. Reproduce the failure with the provided tox command, then verify that DelayedCall.getTime() is epoch-relevant and that the SIP registration test passes.
