Vendor import of tzdata2015c:

Update to tzdata2015c:

    Release 2015c - 2015-04-11 08:55:55 -0700

    Changes affecting future time stamps

    Egypt's spring-forward transition is at 24:00 on April's last Thursday,
    not 00:00 on April's last Friday.  2015's transition will therefore be on
    Thursday, April 30 at 24:00, not Friday, April 24 at 00:00.  Similar fixes
    apply to 2026, 2037, 2043, etc.  (Thanks to Steffen Thorsen.)

# Egypt will start DST on midnight after Thursday, April 30, 2015.

# For now, guess that later spring and fall transitions will use

#
# - [1] says SMT was -4:42:45, [2] says Chile's official time from

# Astronomical Observatory (OAN), then located in what is now
