If you are worried about wasting processing power, it's not really significant enough to worry about. Time calculation happens regardless. It's only wasting 1 operation by writing the updated second. The AM/PM doesn't get updated every second.This is one of my many optimizations. It only gets calculated and updated when the thing needs changing.
However, having said that I like your blinking dot idea. I'll put that on a feature list here... not sure when the next revision will be though. lol
Sweet!
Looks like that bit of processing will be put in good use then.
I'm looking forward to it. I don't mind to wait for it since I won't be changing lock screen any time soon =)
Thanks.
