Test DurationFormatUtilsTest.testEdgeDuration fails in JDK 1.6, 1.7 and 1.8, BRST time zone

While helping testing LANG-942 with JDK1.8 I always got three tests failing, while others had 2. After @britter fixed the issues related to JDK1.8, I continue getting errors with JDK1.8.

I decided to vote for [lang] 3.2.1 and test the tag with JDK 1.8 and a few others. However, I'm getting errors with any JDK, 1.6, 1.7 and 1.8 (build 121). Always the same error:

Failed tests:
DurationFormatUtilsTest.testEdgeDurations:467->assertEqualDuration:562->assertEqualDuration:575 expected:<7[7]> but was:<7[6]>

I get the same error with JDK 1.6 and the tag 3.1

Since the test is somewhat related to Time Zones (there are some Calendar's, TimeZone.getDefault(), etc), here's my locale and time zone:
