I've implemented the 1588 protocol a couple of times, and I have less optimism. This "era" thing seems like the exact type of thing that someone would ignore when implementing the protocol, or if it is supported, probably doesn't get tested much. It's like leap seconds. Yeah, the leap second info is conveyed in PTP, but most of the implementations I've seen simply ignore it and just jam the clock when the time jumps.
