Details:
Busy central machines (such as redirectors or EOS namespace nodes) will log
several hundred messages per second.
Attempting to reconstruct an event flow with logs from other services (e.g
data servers) means that lots of unrelated messages will sit next to each
other after sorting, and (unless explicit precautions are taken), a naive
sort will reorder messages even from the same server.
Correlating such logs would be much easier if the logs were to have at least
millisecond precision. Microsecond would be even better - NTP will give us
this level of precision, so "time order" would be still meaningful across
machines, and accidental re-ordering of messages via sorting would become a
non issue.
