Depends on how good a time source you want. I tested routers as NTP servers and the stability is poor. They respond to NTP pings at a low priority and, when the cpu gets busy, the dispersion goes through the roof because of the delay messing up the symmetry of the transmit to reply times. Of course, this is usually transient, but routers (or at least Cisco routers) are not good NTP servers. R. Kevin Oberman, Network Engineer Energy Sciences Network (ESnet) Ernest O.
