Bug ID: 54686
           Summary: LibvirtTool sometimes fails to update the time
           Product: Wine-Testbot
           Version: unspecified
          Hardware: x86-64
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: unknown
          Assignee: [e-mail]
          Reporter: [e-mail]
      Distribution: ---

When reverting to a live snapshot it is necessary to update the VM's time so
certificate checks and more work as expected. This is handled by LibvirtTool.pl
via using the SetTime TestAgent RPC.
However there are some cases where this fails as is evidenced by job 130592:

w10pro64v2004 LocalTime: 2023-03-14 2 10:47:10.744
w10pro64      LocalTime: 2022-12-11 0 14:18:16.343
w10pro64_fr   LocalTime: 2023-03-14 2 10:46:42.143

So the time did not get updated on w10pro64 while it did get updated on all of
that job's 4 other VMs. Furthermore there is evidence that during that day's
nightly WineTest runs it is w10pro64v2004 that did not get a time update (or
the time reverted back?).

Failure to update the time can cause test failures so it needs to be reliable.
