PBX in a flash is well known free open source PBX system. In this article I'm going to explain how to set the system time correctly and how to let it sync with a NTP (Network Time Protocol) server. Which will sync my PBX systems time with selected internet time servers automatically and will keep the correct time always.This will allow you to apply day light saving settings (If you're in US) automatically and will allow "Time Conditions" to run properly on the PBX. To do this I'm going to use a web based tool called Webmin which will install automatically when you're installing the PBX.
