Vnstat time not correct

[Bai Shen]

I was looking at vnstat to check my bandwidth usage.  When I looked at the 24 hours of usage, it was off by about five hours.  Figuring the time on my pfSense box was wrong, I ran date, but it was set correctly.

Is there a time configuration part to vnstat?  The only thing I can think of is that it's not taking into account the time zone.
