Subject: | [Qemu-devel] Bug: When setting hardware clock on linux guest, hwclock shows crazy date (in the year 2043) |

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'")
