Applied fix from trunk for revision: 1580455 
===

Fixed a bug in a test case that was causing a test failure when a Daylight Saving Time change was scheduled within a week: the test was trying to accept a +/1 hour difference but since the unit of measure of time was milliseconds then it had to be +/-60*60*1000=+/-3600000 
Thanks to Christian Geisert for the fix.
