I'm finding that the latencies I'm trying to measure are less than the differences in NTP-synced time, and this leads to very misleading graphs.

1. Does anyone have any suggestions for a good, but not-too-expensive, GPS time source to use with perfsonar/CentOS?

2. Is it possible to configure perfsonar to graph the sensitive packet loss from owamp, but hide the latency? (I can always use ping for round-trip latency)

Thanks,

Brian.
