1. A method of synchronizing units of a formation evaluation/drilling operation evaluation system, comprising:
- determining a time delay associated with a communications link between a master unit and a slave unit of the formation evaluation/drilling operation evaluation system, wherein the master unit has a master time clock that provides universal time; and
using the time delay associated with the communications link to enable synchronization of time provided by a slave time clock in the slave unit to the universal time.

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.

20. A system comprising:
a tool to perform an operation in a well or with respect to a subterranean structure, wherein the tool comprises; a master unit having a master time clock to provide universal time; a slave unit having a slave time clock; a communications link connecting the master unit and the slave unit; synchronization logic to determine a time delay of the communications link, wherein the time delay enables a time provided by the slave time clock to be synchronized to the universal time. - View Dependent Claims (21, 22, 23, 24)
