Take some time....

I'm not sure how "smart" this clock will be, and if it will run on time on your computer.
You can use the slider to adjust the time zone.
Just think a bit about clocks and this question...

At approximately what times do the hour and minute hand of a clock make a right angle?
Note, some of these will be at NICE times, like, for example, 3 o'clock.
(and there's one answer)

But there will be some messy answers too.
Try to find them all... even if you have to approximate for the messy answers.

(it is possible to get all the EXACT times, but that takes some pretty high powered math.
For now, just figure out the approximate times)
