 $ ln -s /usr/share/zoneinfo/Europe/Athens /etc/localtime
 $ date
 Mon Aug 17 01:38:22 EEST 2009
 $ TZ=UTC date
 Sun Aug 16 22:38:23 UTC 2009
 $ gpspipe -r
 ...
 $GPGGA,193856.00,,,,,0,00,,,,,,,*48
 $GPRMC,193856.00,V,,,,,,,160809,,*19
 $GPGLL,,,,,193859.00,V*27

 That's 19:38, which is yet 3 hours from UTC in the wrong direction.
 it'd be 20:38 had I used Europe/Amsterdam and 22:38 without any
 /etc/localtime.

 I don't know whether gllin/chip is fed the wrong time at startup to look
 at its satellites, or whether it is making a mistake itself.

 Consequences are that otimed will use this wrong time after a while; the
 change can be found in /var/log/frameworkd.log at INFO level, and after
 the change the timestamps in that logfile used as prefix have changed.

 Bye,
 Kero.
