Bug 797139 - test-report-utilities failure after 10-march in travis

gnc_dmy2time64_neutral is TZ-insensitive whereas gnc_dmy2time64 and
gnc_dmy2time64_end are TZ-sensitive. Using _neutral mixed with others
will occasionally cause test failures when the dates straddle DST
boundary dates.

Please see bug report on bugzilla for full details.
