Hmph. Checking on my Pi I get a completely wrong TZ because my preference ‘useLocale’ is false. The code in Locale>startUp: dates back to 2005/8 so it’s unlikely to be wrong without having been noticed. 

Hmm, even weirder - it’s not a preference I screwed up so far as I can tell since it is the same in a plain 5.0 image on my iMac. Which makes me wonder why the menubar time is correct…

Oh yuck. DateAndTime>now uses nowWithOffset: and the (wrong) offset. The ClockMorph uses Time>now which works from millisecondsSinceMidnight and uses the old prim 135 millisecond clock in an original 5.0 image and localMicrosecondClock in a recent update. So the TZ is getting added at the primitive level and we have confusion. Is it really a good idea to have a primitive using the OS idea of TZ as well as image code using its own idea of TZ?

The net effect with latest updates installed is - 
DateAndTime now 2016-02-16T18:56:54.67808+01:00
Time now 10:56:51.64374 am
