Normalize new Duration instance if signs of seconds and nanoSeconds do not match. Fixes invalid printString for Duration in this case. DurationTest>>testNormalizeNanoSeconds passes now.
=============== Diff against Kernel-ul.485 ===============
Item was changed: ----- Method: Duration>>seconds:nanoSeconds: (in category 'private') ----- seconds: secondCount nanoSeconds: nanoCount "Private - only used by Duration class"
