Planning for time travel isn’t as easy as you might think

It is my intention to travel in time in about three days.  My plans are as follows:

On Thursday December 9, 2010 I plan to travel back in time 3 hours along my personal timeline.

On Sunday December 12, 2010 I shall travel forwards again by 3 hours.

Upon meeting people I shall declare unto them, “Lo!  I am from the future!  And it is a glimmering shiny place!  I cannot wait for you to see it!”
