Re: NTP
I do not beleive the Procurve 5400zl's can act as a master the way Cisco Can.
If you want the 5406zl to be a client running ntp as the time protocol.
then do the following:
sntp unicast
sntp
timesync sntp
then set your server you are pointing to. you will have to set your time zone and DST rule as well.
Cheers,
Trev.

Re: NTP
You need an external timesource
- hardware device (radio receiver)
- server
- internet source like ntp.org
ntp also comes in versions, check if you use the same ntp version as the ntp-source.

Re: NTP
1. Limit the devices connecting to the internet for NTP data. This reduces the load on the public servers and also increases security. Our firewall cluster from Juniper can act as NTP client/server to internal hosts and I imagine other firewalls and security devices can do the same.
2. Use the excellent http://www.pool.ntp.org/en/use.html website to locate public servers to configure ntp on these master devices, I'd suggest you use ntp servers in your locality (same country/continent). Remember to setup more than 1 ntp pool entry to check. I check 3-4 public NTP servers via pool entries.
3. Get all of your other internal devices to connect to these master devices on your network.
4. The commands I use for HP switches are...
sntp server [ip address]
timesync sntp
sntp unicast
5. If you need ultra precise timing you may have to invest in your own stratum 1 server. However the ntp pool website is sufficient for most needs.
