Abstract

A circuit arrangement and a method for synchronizing clocks in a network is provided, comprising a plurality of at least two nodes, wherein at least two of said nodes can communicated with each other and each have a local clock, wherein, in a receiving one of said nodes, from at least one transmitting other such node, a global time transmitted by said transmitting one of said node of said transmitting one of said nodes is received, and a global time of said receiving node is determined or estimated as a function of both the received global time of said transmitting node and of a local time of the receiving node's own local clock.
