As the Canadian Hydrogen Intensity Mapping Experiment (CHIME) has become the\nleading instrument for detecting Fast Radio Bursts (FRBs), CHIME/FRB Outriggers\nwill use very-long-baseline interferometry (VLBI) to localize FRBs with\nmilliarcsecond precision. The CHIME site uses a passive hydrogen maser\nfrequency standard in order to minimize localization errors due to clock delay.\nHowever, not all outrigger stations will have access to a maser. This report\npresents techniques used to evaluate clocks for use at outrigger sites without\na maser. More importantly, the resulting algorithm provides calibration methods\nfor clocks that do not initially meet the stability requirements for VLBI, thus\nallowing CHIME/FRB Outriggers to remain true to the goal of having\nmilliarcsecond precision.\n
