Time-traveler.
About 2/3 of the time I travel into the future at a rate of 1 second per second, but about every 16 hours or so I travel forward 7-8 hours in a wink.
I've watched technology and culture change. I've seen computers move from data centers into just about everyone's homes. When I started my travels we had a black and white television in our house. I remember when MTV was formatted like a radio station, but with videos.
I've watched babies born and grow into adults. I've watched adults grow frail and die.
I can't travel back in time, and the closest I can come to adjusting the settings is to either waste time, or do something with it.
It's frustrating that I age just about as fast as I travel. I can see that so much time passed before me, and so much is going to pass after. I can see the Mars rovers exploring a place that I won't because of how slowly I time-travel, and how quickly I age.
Everyone else I know is the same kind of time-traveler as I am, but most people don't like to dwell on it.
