Yes, it will. But ntpdate does much more than fix the time and date. It observes clock drift over a long period of time and applies constant corrections to the slew rate of the clock even when you are no longer hooked to the internet. And when you are hooked to the internet, it is constantly nudging your time to the correct time instead of providing gross jumps which can mess with computers that are doing time sensitive work. It also takes into account latency of the internet so when you are checking time through a connection that is suddenly lagging terrible, it will throw those corrections away until it gets better ones. In short, it's more accurate more often than cron jobs that make your clock jump. -- "Ninety percent of politicians give the other 10 percent a bad name." -- Henry Kissinger
