The right time synchronization is very important while troubleshooting different kind of problems. Most network components have the option to synchronize their time with a time server on the internal network or the internet. This post shows how to configure NTP with the right time zone on Cisco and HP ProCurve components. The example configurations use the NTP servers from pool.ntp.org.
