Techniques for comparing atomic frequency standards at uncertainties of less than 1 x 10-15 are reviewed. These techniques include the impact of displacements in both time and space. The additional uncertainties contributing to the comparison process using current technologies in stable frequency references and in long-distance frequency (time)-transfer techniques are quantified. As an example, the results of frequency comparisons between a pair of cesium-fountain primary frequency standards are given.
