Look at the amount of days left in my premium membership, provided it hasn't expired yet.
Look at it.
It's back. The zombie of the worst, most illogical number in history. A number so fucking unholy that it only shows up in computers and weird calculus.
Just based on the fact that the number has even reached -0 rather than -1, we can probably assume that it is storing the time left in a value lower than days, most likely milliseconds based of the standard Unix epoch. It appears to switch from 0 to -0 the day that the premium membership will expire even if there is still time remaining left, which should make it stay 0.
I have no idea.
