The following patch will be in the next release of e2fsprogs. If
you'd like to apply it and rebuild it, it will provide the proof you
need that either your laptop RTC clock is bad or there's something
strange going on with the system time on your laptop.

e2fsck: Fix and enhance superblock dates in future problem reports
Fixed a bug where e2fsck would report that last mount time was in the
future when it was really the last write time that was in the future.
Also, since people can't seem to believe that (a) their distribution
has buggy init scripts, or (b) their CMOS/RTC clock or backup battery
is dead, print the incorrect time and the current system time.
