    NTP works well. There's a list of potential servers at:
    It handles the correction for roundtrip delay automatically.

    I use NTP on my laptop and other computers (both at home and at work). NTP
    will work quite well as long as you're connected to the network.  I'd rather
    use an NTP-synchronized computer to set my watch and then use the watch
    for navigation since the drift characteristics of my watch are better
    known the laptop's. Clocks on a computer can change drift characteristics
    depending on cpu activity, battery voltage, temperature and so on.
