For those alarmed at the offset... # yum install ntpdate # ntpdate -u ntp-1.vt.edu # hwclock -w "Your time is exact!"

  This is an unobtrusive app that does the job for Android (root required/recommended): https://play.google.com/store/apps/details?id=ru.org.amip.ClockSync&hl=en https://play.google.com/store/apps/details?id=ru.org.amip.Cl... My ZTE Blade/CM7 was obnoxiously bad at keeping time, probably a software bug or something.

    Not sure why Android does not have ntp built in. My network does not broadcast a time signal, maybe it is just assumed they all do.

      Your cell network or you do not have multicast ntp enabled?
      • justincormack 15y ago
        Cell network doesnt broadcast time. You can install ntp client, but it needs to run as root, and I wont let anything from the market run as root, and I havent got around to building an ntp client myself...

  ntpdate is dead and is discontinued. Use an actual daemon to govern your time source. I thought redhat installed ntpd or chrony by default. I know chrony is the default for the next fedora release. If you have ntpd/chronyd installed your advice is horrible and not just because you pointed everyone to Virginia Tech's time server.

    Thanks : Updated procedure (for Fedora without chronyd/ntpd running already) : # yum install chrony # systemctl enable chronyd.service # systemctl start chronyd.service Sorry if the (working) pointers before were horrible. Hopefully this is more useful - the servers used are {N}.fedora.pool.ntp.org.

      chronyd is a lot more mindful of battery/power considerations than ntpd. It is an interesting approach to endpoint time synchronization compared to the ntp reference implementation.
