Yesterday I found this interesting code-puzzler on java.dzone.com:

How Many 1's Appear in A Binary Clock Across an Entire Day

Say you have a binary clock, where 09:30:22 would be displayed as

Hour: 00001001
Minute: 00011110
Second: 00010110

Calculate the number of 1's that would appear over the course of an entire day of military time starting from 00:00:00 all the way up to 23:59:59

My last entry was: 

while(1){$_+=(unpack"%32B*",pack"i3",gmtime++$i)||last}print

I'm sure it's possible to shorten that.

Why not give it a try!

s$$([},&%#}/&/]+}%&{})*;#$&&s&&$^X.($'^"%]=\&(|?*{%
