Hey. You knew that. Don't you?

Manipulate time itself?
You must choose a very 'unusual' time, which has to be a dynamical
variable, like tau, the 'proper' time of a particle. In this case you
could write, safely enough, an uncertainty relation like
        Delta tau x Delta mass of the particle =/> h
which should be, more or less, the target of any serious space-time
quantization program. Note that if you measure, or impose, a small
Delta tau, the Delta mass of the particle becomes very large, and
viceversa.
Not much different from the usual position vs. momentum relation
            Delta position x Delta momentum >/= h
by which, changing continuously Delta position you reveal the
particle-like nature, or the wave-like nature, of the 'thing'.

The other classical possibility, given the SR metric, is represented
by the weird uncertainty relation space vs. time, like
        (dx/dt + ds/dt) x (dx/dt - ds/dt) = 1/c^2

Not to mention what would be a Universe dependent on the
Banach-Tarski paradox on unmeasurable sets for its operation!
(But this would really be magic).
