port to time-1.5

ehem... you might want to consider using pvp ;-)
When the flag defaults to true, it will try to install time-1.5 even when time-1.4 is installed. That leads to reinstalls when people are not using sandboxes.

Personally, i don't care. I always sandbox. So i can do whatever you like.

Regarding the alignment. Sorry for not noticing. I will update the pull request monday.
