same here, dump the world clock unless there is another solution that works good with locking the device. It seems like the 6.5 lockscreen conflicts with the htc and tachi dialers but of course these dialers are nicer than the wm dialer. so it's all about tradeoffs. I wonder if there is a better locking solution that could be implemented in lieu of 6.5 lockscreen like pocketshield, s2u2, throttlelock, classic lockscreen, etc. Having said this, I really like the 6.5 lock screen, but for the sake of now, i agree! Sorry for the long answer
