So I took that image and the latest CogVM from the download page and tried on one of our Ubuntu 12.04 64-bit machines. I can't make the test fail, I even ran the full test suite. So, not reproduceable from my point of view. Sven

What I do not see is how to achieve this without a cost at runtime. Given that it should support imports.

I looked at it and I can't imagine why this would randomly fail on Mac OS X. But everything is possible. Maybe something with time zones, but as far as I can see, both date parsing and date creation from seconds use the local time zone. As for the test code itself, testGeneralInquiries | now d t dt | now := self timeClass dateAndTimeNow. self assert: now size = 2; assert: now last <= self timeClass now. self should: [ self timeClass timeWords ] raise: MessageNotUnderstood. d := '2 June 1973' asDate. t := '4:02:47 am' asTime. dt := self timeClass dateAndTimeFromSeconds: (2285280000 + 14567). self assert: dt = {d. t.}. The middle part is a GREAT example of a useful unit testâ¦ Sven

Re: [Pharo-project] Next step in cleaning DataStream

good idea. And for fuel we should really see how to support migration between formats.
