A bit of context might help - otherwise the best answer you will get is that York Time is British Summer (huh!) Time at present and will go to Greenwich Mean Time in a few weeks

 

I think it is a method of thinking about the time in lorentzian geometries in which there is assumed to be a constant mean curvature CMC which is proportional to the time

 

The original paper is this York, J. W. (1973). "The role of conformal 3-geometry in the dynamics of gravitation". Phys. Rev. Lett. 28 (16): 1082–1085

 

 

 

Hopefully AJB will swing by - it seems like his sort of thing

I believe York Time would likely represent the slope of the curvature in the spacetime density at the point in the warp bubble.
