well, that might sound appealing at the first glance,
but trust me, that's nothing you really want, for
several reasons:

 - the time system inside the kernel is fairly complex,
   to virtualize it per guest would add significant
   overhead just for doing time keeping

 - there is no point in having 'more' than one time
   base in a single kernel, once it is correct, the
   entire system will have precise time

you can, just install a time deamon which is system
independant or add another layer of virtualization
if you do not care about the overhead

but IMHO, the real solution to your issues is to
kindly ask the ISP to start an ntpd on the host (or
on a special time guest) to synchronize that
