We are told that if the discovery of neutrinos travelling faster than light stands up our understanding of the time space continuum goes for a burton and time travel into the future or the past will become the new reality.

In the fast moving world of telecoms they are already there.  I got a text from Vodaphone this morning telling me that I had three days left in which to use some bonus they had given me as a reward for having topped up my phone.

Fifteen minutes later by the old Einsteinien  method of reckoning a second text arrived telling me that the bonus had now expired.

Where Vodaphone lead Skype cannot be far behind.  They've just sent me an email saying that a credit I have with them will expire in 30 days, so I suppose I had better get my skates on and make a call before lunch.
