Default Time Offset (Hours):
Unadjusted Server Time: 05/25/16 10:16 PM

So my server time is PST, so at the time of this writing 2:16 PM
I got a complaint that the message board was showing messed up times, so I looked and the message board was showing:
Unadjusted Server Time: 05/25/16 10:16 AM

I then set the adjacent field to -8 and it went to:
Unadjusted Server Time: 05/25/16 10:16 PM

What the heck ..
Any ideas?
