[libvirt] [PATCH 2/8] virtime: Resolve Coverity DEADCODE
Coverity complains that because of how 'offset' is initialized to
0 (zero), the resulting math and comparison on rem is pointless.
According to the origin commit id '3ec128989', the code is a
replacement for gmtime(), but without the localtime() or GMT
calculations - so just remove this code and add a comment
indicating the removal
