How to synchronize time on virtual linux server running occasionally?

  • 772

I have following setup for web development: Windows laptop with Microsoft Virtual PC 2007, in it i have Centos virtual machine.

Problem i have is that every time when laptop goes to sleep with virtual machine running or every time i close virtual machine using Save state and then start it again it is stuck with time before it went to sleep.

If i restart OS in virtual machine is syncs its time with host operating system, what i also want to add it ability to do it regularly to avoid time drift.

    You can try using ntpdate, which may be in /usr/sbin or /sbin:

    sudo ntpdate pool.ntp.org

    For more info try:

    man ntpdate

    I hope this helps.

  2. try running ntpdate when you bring the server up, or run it every 15 minutes out of cron:

    (eg */15 * * * * * /usr/sbin/ntpdate)
