Thursday is code puzzler day here at DZone. The idea is simple: solve the coding problem as efficiently as you can, in any language or framework that you find suitable.

Note: Even though there really is nothing stopping you from finding a solution to this on the internet, try to keep honest, and come up with your own answer.  It's all about the participation!

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
