Time Zone Africa/Casablanca staying in DST

Solution In Progress - Updated -

Issue

  • tzdata package does not account for DST changes for Morocco
  • The Moroccan government recently decided to keep DST year-round. As it stands, tzdata package versions up to tzdata-2018f-2.el7.noarch.rpm, tzdata-2018f-1.el6.noarch.rpm, and tzdata-2017b-1.el5.x86_64.rpm do not reflect this and will instruct the server to leave DST on October 28:
