is there a time operator (not the time evolution operator) in standard qm?(adsbygoogle = window.adsbygoogle || []).push({});

I'm a bit curious as while it might not matter all that much for non-relativistic qm it seems as if it would be important to have some measure of a the probability that a particle is at a given place and time.

If I had to guess at one I'd say that its something like i (partial with respect to t) in the position basis.
