Hello Script Wizards!

I'm looking for a script that will change the current time to whatever key frame I have selected.

For example, in the graph editor, I'm on frame 30. I select a key on a curve on frame 50, run the script, and it will change the current time from 30 to 50.

I'm trying to write the script myself but I don't know how to query the time from a selected key frame. My scripting skills are weak! Any help will be appreciated.

THANK YOU!
