Update to tzdata2015d:

Release 2015d - 2015-04-24 08:09:46 -0700

  Changes affecting future time stamps

    Egypt will not observe DST in 2015 and will consider canceling it
    permanently.  For now, assume no DST indefinitely.
    (Thanks to Ahmed Nazmy and Tim Parenti.)

  Change affecting past and future time zone abbreviations

    The abbreviations for Hawaii-Aleutian standard and daylight times
    have been changed from HAST/HADT to HST/HDT, as per US Government
    Printing Office style.  This affects only America/Adak since 1983,
    as America/Honolulu was already using the new style.
