test-parse-date: defines explicit start/end dates for DST
Prior to this patch, DST times where tested by specifying a custom TZ
environment variable that didn't defined DST transition times.
Due to a bug in glibc, the test fail on 32bits platforms that use timezone
files generated by zic from tzcode >= 2014c (glibc >= 2.20).
See https://sourceware.org/bugzilla/show_bug.cgi?id=19738
By defining explicit transition times for DST in the TZ environment variable,
the test is now independant to how the system guess those transition times.
