Ok, here's the deal. I'm always running to the train because I do things at the last moment, so I have an idea for an app that prevents this.

Since I use my phone as my only clock, and I don't have another at home, I would like to request an app that changes the time.

Idea:
At a chosen time, like 4AM ( you can chose whatever time you want ) the app changes your phone clock randomly forward 1 - 10min ( you can chose whatever interval you want ), that means that you never know how much in advance your clock is, it could be 3min or 9min, then you need to stick to the time your phone shows.
Et voilà, never late again.
Is this possible? Anyone out there that would like to make one/has a need for one themselves?

I would make it myself, but my programing skillz are close to zero.
