In this paper we address the problem of translating timestamps found on multiple
computing systems to a common reference time. We describe results from
experiments where we observed the clock of a simple computing system, and then
present a computer clock model. The model we introduce addresses certain
shortcomings of an earlier model by Stevens and offers an intuitive approach for
describing computer clocks. The model provides explicit means to translate
timestamps retrieved from computing systems to a common reference time, as well
as an algorithm to iteratively build a device's clock description. A simple
proof-of-concept implementation is also discussed briefly.
