HOWTO use a time server

on MacOS its simple (OsX > select “set time and date automatically” in the date and time system preferences..). if your timezone is set properly it should “just work”

a bit more simple on GNU/Linux/other-n*x. just run 'ntpdate <time-server-address>' but you might need to set the locale and tzinfo.
