Then you should move ;-) Of course, if a functional object (your local timezone) exists in your image, it should be able to print itself. That is a bug that we should fix. Your suggested solution is good. The Timezone class>>#timezones table is very bad though. As is the class Timezone by the way. This class is a simplification gone too far. It is only useful (and used) to deal with the current offset today, as reported by your VM/OS. Timezones need DST transitions. Also abbreviations and the names used are not unique and cannot be resolved in 2 directions. The real solution is something like ZTimestamp's ZTimezone which uses the Olsen database http://en.wikipedia.org/wiki/Tz_database. You can load this package from the Pharo Catalog. It has a certain size (memory cost), of course. But that would still not fix the problem with abbreviations not being bidirectional. (an offset of 1h can be any of a number of abbreviations). And it would not solve the problem with timezone offsets in ISO. (+0100 can be tons of timezones, with potentially different rules). Something like the following would be self-containted/context-free unambiguous. 2017-11-22T09:50:17+Australia/Sydney But as far as I know, there is no such standard (it is not part of ISO 8601).

To reproduce this, start up Pharo, create a Playground, and in the Playground type DateAndTime now timeZone and <Cmd+p> to print it.
But do this in New Zealand. Changing to <Cmd+i>

Inspector on a TimeZone (error printing) ... self error printing offset 0:13:00:00 abbreviation nil name nil
The simplest possible change would be to make TimeZone>>abbreviation be
^abbreviation ifNil: [offset printString]
after which DateAndTime now timeZone<Cmd+p> => a TimeZone(0:13:00:00)
Another approach would be to paste
self offset: 12 hours name: 'New Zealand Standard Time' abbreviation: 'NZST'. self offset: 13 hours name: 'New Zealand Daylight Time' abbreviation: 'NZDT'.
into TimeZone class>>timeZones
but that wouldn't fix the problem for anywhere else.
