Buffalo TeraStation TS3400D User Manual page 189

If an NTP server is specified by name instead of IP address, make sure that a DNS server is configured for the
TeraStation.
Note: The internal clocks of the TeraStation and other devices on your network may run at slightly different
speeds. Over a long period of time your network devices may show somewhat different times, which can cause
network problems. If clocks on your network vary by more than 5 minutes it may cause unexpected behavior.
For best results, keep all clocks on the network set to the same time by adjusting them regularly, or use an NTP
server to correct them all automatically.
