Hi Sagar,

Thanks for reporting this!

I suggest also to evaluate using "GetTickCount64()" in place of the WMI call:

HyperV Driver - Fix to implement hypervisor-uptime

    The hyperv driver currently does not return the hypervisor-uptime.
    This fix does the necessary changes to return the hypervisor-uptime.
    The uptime returned is in similar format to libvirt driver uptime

    The uptime is calculated using the windows function GetTickCount64
    More details about this function available at
    http://msdn.microsoft.com/en-us/library/windows/desktop/ms724411%28v=vs.85%29.aspx

The function GetTickCount64 returns in millisecs the time since the host
is up.
