Description

The spacecraft provides a "1-PPS time hack" interrupt each second (i.e., one pulse per second). When awakened by this interrupt, this task updates the processor's local time value. It works cooperatively with the Spacecraft Attitude/Time slave task (shared memory structure) to build time interpolation tables.
