### [T-(t), T+(t)] != 0 ?

Is the time operator non-communitive? In other words, is the operation that allows time to go forward non-communitive with the operation for when time goes backward?

Normally, we absorb the operator into the variable t and then just not worry about it. But given a space-time coordinate, is the operator that moves t communitive? Space seems to be, but time's a bit screwy, and it may not be. I'm not sure yet; if [T-(t), T+(t)] != 0, then I think I have an experiment in mind that can test if it is true...
