DJGPP uses TZ to figure out what your system clock is set by.  Thus,
no matter what you set TZ to, your system clock should match
localtime() and not gmtime() (unless you're GMT+0).

The zoneinfo files are used to try to figure out how much your system
clock is off by, so that it can figure out what UCT really is for you.
This is done so that when you unzip or untar a file, you get the
correct timestamps.
