I also haven't been affected by the clock bug
I even tried to recreate the problem by leaving my box off for extended periods of time - maybe it only affects certain 1.6, but I'm too lazy to go checking up on past posts
I also tried faulty boot sequences using teh eject and power buttons, etc. to get the recovery mode thing and all
the only thing that happens is that the time/date gets messed up but XOS still boots normally
I wonder what's the real story behind this clock bug.....
