I made this pretty extension (view attachment) for PS CS6 - CC2015 that shows current time as hexadecimal value, and uses the value as its background color.
Not only its beautiful, but can be actually useful, since you can switch to stopwatch mode and measure the time working on a project.. Can be resized to fit your workspace.
Live preview and download link here (It's free download.): http://bit.ly/hexClock
The download file has it's own installer so you don't need any other sofware to install. Enjoy smile
It's not my idea, I think here is the original web version: http://www.jacopocolo.com/hexclock/
I just thought I must have this in my Photoshop.
