Now I'm more fighting with
(Duration readFrom: '0:00:00:00.001 ' readStream) nanoSeconds -> 1
http://code.google.com/p/pharo/issues/detail?id=1202
as well as
self assert: (DateAndTime readFrom: '1901-01-01T00:00:00+12:00'
readStream) asString -> '1901-01-01T00:00:00+02:00'
;)
which works in squeak!
