Steps to Reproduce

I started up storjshare at a time where my internet happened to be down. My initial guess is that's how it can be reproduced, but I have no easy way to test this at the moment.

I need to pull moonpyk/node-ntp-client#6 into my fork

[161chihuahuas]

Done. https://github.com/bookchin/node-ntp-client/commit/9edb9e3c44aa5ccd963e19cd709191a2dc07e2ea

Re-installing deps should fix this issue.
