Cataclysm-dda: Cloth roof installation time is negative

[CR2041]

Vehicle construction menu lists install time for cloth roof as "-128849016 seconds". Attempting to install a cloth roof results in my survivor working on the vehicle until he dies of dehydration; even being interrupted by a 'You're tired' prompt doesn't stop the construction.

We've done it. We've discovered post-apocalyptic time travel. Your survivor travelled back in time to before he was born.

I'd die of dehydration too if I had to install a vehicle part for four point something years.

I'm pretty sure I also have this problem installing a travois.
