Bug#1092102: kalarm ftbfs on armel, hppa and other 32-bit platforms

[Helge Deller <deller@gmx.de>]

Package: kalarm
Version: 4:24.12.0-2
Tags: ftbfs
Usertags: hppa armel armhf i386

kalarm fails in some testcases on 32-bit platforms like this:

FAIL!  : KADateTimeTest::constructors() Compared values are not the same
   Actual   (datetimeTz.qDateTime())    : 2001/02/13 11:45:14.000[GMT]
   Expected (dtLocal.toTimeZone(london)): 2001/02/13 03:45:14.000[GMT]
   Loc: [./src/kalarmcalendar/autotests/kadatetimetest.cpp(457)]

In debian/rules this line:
  testsuite_failing_archs := armel armhf i386
disables the checks on the mentioned platforms (why were the others like m68k, powerpc and such left out?).
But this just hides a problem I assume.

Does anyone has an idea why those tests fail?
Has someone already analyzed?
Is it related to the time64 transition?
