The Sysadmin’s Daily Grind: HTPDate
Despite the cyclical disruptions so typical of LUG meetings, our intrepid columnist, Charly, reveals how he set the system time in spite of a blocked NTP port.
I am writing this article from the LUG Camp at Wuppertal Germany, and the time is… – er, I have no idea. A kind person from the LUG Flensburg hands me a bottle of Flensburg beer, and I say “Thanks”… Enough has already been said about NTP (Network Time Protocol) based time synchronization, and in fact, I confess to having written about NTP in the past. But today, I will discuss how to time sync without NTP. Up curtain and welcome to HTPDate  Of course, NTP is the tool of choice if you need to sync the system clock across a network. But there are times when network synchronization is not possible. For example, if the machine you need to sync is hiding behind a totally hardened firewall maintained by a totally hardened admin who says things like “NTP? Never heard of it, so it must be something bad!”
