Yeah but I usually fix what I break. Because I need the things to be working
again if I want to happily continue breaking them :o)

/me wonders if he hasn't played too much legos when he was a child. That
may have provided him a strange vision of the world.

That said I've tested timechart few days ago and it worked very well. (That
was also the first time it worked for me).

So I guess it should be fine.
