The Republic Measures & Standards Bureau (RM&S), a division of the Galactic Republic government, had the duty of overseeing consistent measurement units. This encompassed time, and it is thought that it also covered weight, currency, and other comparable values. They handled the time standardization known as the Great ReSynchronization, and it is believed they also established "Year 0" on the calendar with the Ruusan Reformation.
