While monitoring GMT Y2K progression on a Cisco router, something curious
showed up:
[...]
Notice the dot before the time; it was not appearing before, and even on the
first sample after GMT Y2K-rollover (local time is GMT -0200). It now shows
up on every 'show clock'.
This doesn't seem to be a problem with cisco, but if you are synchronizing
to certain NTP servers (i.e. usno or nist) they currently have reachability
problems. So your cisco reports a "." that your ntp is unsynchronized.
I haven't found out if the government networks are deliberately throttling
traffic or if the links to the time servers are just congested.
I have no idea why it started at almost exactly midnight UTC.
