[Bug 1026621] Re: nova-network gets release_fixed_ip events from someplace, but the database still keeps them associated with instances

[Jay Farschman]

We appear to have solved this problem for ourselves by changing the way
windows deals with time.  Remember, the symptom is we are obtaining a
lease from August in 1877.  Seems like this is caused by windows using
local time rather than UTC.  The solution is to change windows to UTC.

Changed the RegKey
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\TimeZoneInformation
and created a new DWORD called RealTimeIsUniversal and set it to one 1.

Now, I believe there may be a problem with this when we enter and leave
daylight savings, but at this point I have a system that boots and keeps
it's IP address.  I may be using puppet to change RealTimeIsUniversal
back to 0 after everything is working.
