Is it possible to write a timer app that shows the timer in real-time on the lockscreen?

I don't fully know how the lockscreen support works, but I don't see why it couldn't have a real-time timer, where it shows the actual time counting down or up. I don't think there are currently any timer apps that offer it, but if you know any, please share.

And please no "why do you want that, just disable the lockscreen" or "you don't need to watch the lockscreen, just wait for the alarm to sound". If you can't make a direct reply to my question, then don't bother.

I don't think you can update the lockscreen often enough for that.
