Re: [EFM]Event Time Stamp
Here's my recollection of the justification of timestamping...
The timestamp is not intended to represent the time since system uptime. At least not for any piece of reliable equipment:) It was added to provide "relative" times between events for more accuracat reporting (e.g. if source timestamps X & Y as happening 500 ms apart, thats probably more accurate than the receiver getting them 650ms apart due to the delay caused by the limited number of OAM frames). The origin of the utility can be found in
