<source lang="xml">
<package id="ntp-client" name="NTP time synchronization" revision="1" priority="999" reboot="false" execute="once">
        <install cmd='cmd /c sc config w32time start= auto' />
        <install cmd='cmd /c net time /setsntp:192.168.0.1' />
        <install cmd='cmd /c net time \\192.168.0.1 /set /yes' />
        <install cmd='cmd /c net stop w32time &amp; net start w32time' />
        <install cmd='cmd /c w32tm /resync /nowait' />
        <remove cmd='cmd /c net time /setsntp:time.windows.com' />
        <remove cmd='cmd /c net stop w32time &amp; net start w32time' />
        <remove cmd='cmd /c w32tm /resync /nowait' />
</package>
