In this paper we argue that achieving symmetric errors is the key to an improved understanding of clock synchronization. We present a clock synchronization algorithm with drift compensation that implements this symmetric error paradigm. The performance of the algorithm is evaluated by measurements in an indoor testbed using the TinyNode hardware platform. We show that the remaining error is symmetric and in the range of the clock granularity.
