Import tzdata2017b from ftp://ftp.iana.org/tz/releases/tzdata2017b.tar.gz

Summary of changes in tzdata2017b (2017-03-17 07:30:38 -0700):
    Haiti resumed observance of DST in 2017 (on Mar 12)

    Liberia changed from -004430 to +00 on 1972-01-07, not 1972-05-01.
    Use "MMT" to abbreviate Liberia's time zone before 1972,
    as "-004430" (tzdata2016a) is one byte over the POSIX limit.

-# For Liberia before 1972, Shanks & Pottenger report -0:44, whereas Howse and
-# Whitman each report -0:44:30; go with the more precise figure.
