I was just prompted to install the latest update to PerfectDisk, the disk defragger that I use on my main PC. It’s a nice, well-behaved piece of software that does a much more thorough job than the built-in tool you get with Windows XP. It also appears to be developed by humans, rather than the Borg. In the release notes that popped up on screen while the update was installing was this little gem:
Corrected a bug in the boot time defragmentation. PerfectDisk records the current time on shutdown and compares it to the system time at reboot. On Windows XP, Service Pack 2, the system time at reboot can be earlier then the system time at shutdown. Raxco was unaware that Microsoft was able to travel back in time.
 Not that I am in any way comparing any Microsoft employees to the Borg
