Claim Text:
1. A method for determining a time representation in a network device, the method comprising: receiving, at a target clock domain of the network device, a master pace signal corresponding to a time representation based on a master real time clock in a master clock domain, the master pace signal being generated, in the master clock domain, at a first frequency; depositing, in a time accumulator in the target clock domain of the network device, a fill quantum of time units based on the master pace signal; decreasing the time units in the time accumulator by a leak quantum according to a local clock signal in the target clock domain, the local clock signal running at a higher frequency than the master pace signal; and periodically generating, at a granularity corresponding to the frequency of the local clock signal, an updated time representation in the target clock domain based on a residual number of time units in the time accumulator before depositing an additional fill quantum of time units in the time accumulator.
