Display showing GMT Linux

My displays are showing GMT instead of EST. Under Admin -> Settings -> Regional I have the timezone set to GMT-5 New York. Under Display -> Edit Settings -> Location I have the correct Lat/Long and Timezone is also set to GMT-5 New York. In my layout, the time shows correct but on the screen, it still shows GMT. Suggestions?

Thanks in advance for any assistance.

Have you checked the system clock on the Player hardware itself? Perhaps that is set to GMT.
