/*
 * Compile with:
 * gcc $(pkg-config --cflags --libs libgpod-1.0) -o tz ./get-timezone.c
 *
 * then run:
 * ./tz <ipod-mountpoint>
 *
 * This should output something like:
 * Timezone: UTC+1 DST
 *
 * which means I'm living in an UTC+1 timezone with DST which adds a 1 hour
 * shift, ie my local time is UTC+2. DST won't be shown if not active.
