US Central time is currently 5hours behind UTC/GMT.

Linux stores the true time in the Real-time clock and keeps track of your
timezone as an offset.  Unfortunately, on PC systems, Windows stores
localtime in the computer's Realtime Clock (RTC).

One solution to this is to leave the RTC in localtime and have Linux adjust
the time when reading or writing it.

There isn't really a good solution, but something will probably be
introduced as a work-around if there's also a copy of Windows on the system.
