Title:
  When setting hardware clock on linux guest, hwclock shows crazy date
  (in the year 2043)

Status in QEMU:
  Fix Released

Bug description:
  Very easy to reproduce:

  1) Build the latest qemu.git (we've captured this on internal
  automated testing, verified manually), the commit for reference is:

  14:07:02 INFO | git commit ID is
  6f8fd2530e9a530f237240daf1c981fa5df7f978 (tag v1.2.0-461-g6f8fd25)

  2) Install a linux guest in it (caught with RHEL 6.2, verified with
  Fedora 17)

  3) In the linux guest, set the hardware clock with hwclock:

  /sbin/hwclock --set --date "2/2/80 03:04:00"

  4) Verify if hardware clock was set back to the eighties:

  LC_ALL=C /sbin/hwclock

  5) Observe amazed that hwclock reports a date in the year 2043:

  14:09:34 INFO |          ('hwclock', 'FAIL', 2, "Failed to set hwclock
  back to the eighties. Output of hwclock is 'Sun Dec 27 20:35:46 2043
  -0.489664 seconds'")
