Jeff Johnson filed bug report #1863171

(http://curl.haxx.se/bug/view.cgi?id=1863171) where he pointed out that
libcurl's date parser didn't accept a +1300 time zone which actually is used
fairly often (like New Zealand's Dailight Savings Time), so I modified the
parser to now accept up to and including -1400 to +1400.
