Relative time

I had a brief moment of questioning my reality in the elevator. I went downstairs to pick up the daily mail and the coffee bar was still open. It's around 12 and I had to do a double take. A co-worker rode the elevator up with me. These are all the elements familiar to me at about 9 in the morning, not 12. For a moment I lost touch with when I was. Sorry Doctor, time travel won't suit me.
