Wallpaper clocks - specs for software developers

If you have software related to desktop management, I encourage you to add WCZ support to your app - your users will get tons of nice desktops showing time and date!

variant 3: clock.ini has That means that the skin includes hour0...hour23.png but you should only take hour0...hour12.png and rotate hour image every 60 minutes (0..12, then 1..11).
variant 4: clock.ini has
