Abstract
This article describes a device which provides the value of date-coordinated universal time (date UTC)! to the JPL Network Operations Control Center, Real-Time (NOCC-RT) facility. The NOCC-RT is the real-time portion of the NOCC upgrade task. The time scale is generated in the NOCC-RT clock processor; however, there is a continuous reference to UTC, as realized by the National Institute of Standards and Technology and transmitted by Earth-orbiting satellites. An important functional design requirement is the 99.9-percent availability.
