%0 Journal Article %T Time Measurement in Quantum Gravity %A N. Itzhaki %J Physics %D 1994 %I arXiv %R 10.1016/0370-2693(94)91479-6 %X We discuss time measurement in quantum gravity. Using general relativity for large distances and the uncertainty principle we find a minimum time interval of the order of the Planck time, therefore the uncertainty in time measurment is bounded from below. %U http://arxiv.org/abs/hep-th/9404123v1
