Hello,Please review the fix for JDK-8152077. There's a bug in the roll method around the standard/daylight saving time transitions. I've changed the implementation to perform the "roll" operation based on the wall-clock time rather than the UTC time (the offset from the Epoch).
Issue: https://bugs.openjdk.java.net/browse/JDK-8152077 Webrev: http://cr.openjdk.java.net/~okutsu/9/8152077/webrev.00/ Thanks, Masayoshi
