All, Looking through timezones.conf.xml some of the lines jump out at me: <zone name="America/New_York" value="EST5EDT,M3.2.0,M11.1.0" /> According to various bits of documentation on this format it appears that the time of day (not day) specifying the change to daylight savings is missing: http://www-01.ibm.com/support/docview.wss?uid=isg3T1000252 Does this mean the line should look more like this: <zone name="America/New_York" value="EST5EDT,M3.2.0/2:00:00,M11.1.0/2:00:00" /> ...or am I missing something? Thanks! -- Kristian Kielhofner
