Comment 2 for bug 422869

At a guess, your Jaunty and Karmic installations disagree about whether the hardware clock should be to tick localtime or UTC time, and one of the things the shutdown scripts do is to set the hardware clock from the system clock. This causes the time at boot up to be incorrect until NTP has a chance to correct things.

This isn't an e2fsprogs bugs, but rather a system configuration error.
