System and method for synchronizing devices. A device reads a first counter coupled to and associated with a master clock and a second counter coupled to and associated with the device, where the device is one of one or more devices coupled to the master clock and each other via a switched fabric, where each device includes a respective clock, and is coupled to and associated with a respective second counter. Each of the first counter and the second counters is accessible by each of the one or more devices. The device determines a difference between the device's associated second counter and the first counter, and determines and stores a time reference for the device relative to the master clock based on the determined difference, where the time reference is useable to timestamp events or synchronize future events.
