Abstract
To synchronize units of a formation evaluation/drilling operation evaluation system, a time delay associated with a communications link between a master unit and a slave unit of the formation evaluation/drilling operation evaluation system is determined. The master unit has a master time clock that provides universal time. The time delay associated with the communications link is used to enable synchronization of time provided by a slave time clock in the slave unit to the universal time.
