On almost any Linuxdistribution, the date & time are set automatically via NTP. It stands for “Network Time Protocol”, and the idea is to sync the clock with another computer (generally from an online server). During the system installation, the configuration wizard will only ask for your ...

Set the priority, which selects the best master clock. You can set priority 1 or 2. For each priority, you can use a number between 0 and 255. The default priority is 255. For the boundary clock, use a number above 128. The lower priority is applied first. Add thetime-stampingparame...
* Run ``date MMDDhhmm'' to set the current system date/time. * Type ``/sbin/hwclock --systohc [--utc]'' to set the hardware clock. Other interesting notes The Linux kernel always stores and calculates time as the number of seconds since midnight of the 1st of January 1970 UTC rega...
