Mark, could we also initialize zoneinfo from config.ini if there's an appropriate entry there? This would allow us to get the right timezone for TTSClock. Or are you saying that we have it by that stage (I'm not sure exactly what stage you mean by "not until after the first startup of the player after boot").

I ought to get around to installing strace myself - I set TZ for TTSclock, but that seems only to affect the DST selection and not the offset; I don't understand why.
