Fix flaky test

[polohan]

Purpose

Resolve issue #154. ConformanceTestV2.testConformanceTestC's IIC103 case will fail when running in a region that has a different timezone at 2001-01-22T08:23:47-05:00 and at 2002-03-22T08:23:47-05:00.

Goals

Fixing the test so that it won't fail when running in every timezone.

Approach

Without changing the original code, the most simple fix would be modifying the test case. And afaik, no region will switch between DST and standard time between Jun and Aug so simply advancing both dates by 5 months should fix the problem.
