Time Travelling

2.31am (GMT+1), Sunday, 28th October
Jamie and Jith have some friends over in the living room. K is a tea fanatic. Stephen has an iPhone.

K: Can I have some tea?
Jith: No! It's way too late. If you'd asked an hour ago you could have had some.
K: ???
Jith: If you go back in time and ask me an hour ago you can have some tea then!
Stephen: [Checks phone] ...oh. It's one o' clock. The clocks have gone back.
K: Can I have some tea then?
Jith: Yes, you may.
