"This update includes the changes in tzdata 2019a. Notable changes 
are :

  - Palestine started DST on 2019-03-30, instead of
    2019-03-23 as previously predicted.

  - Metlakatla ended its observance of Pacific standard
    time, rejoining Alaska Time, on 2019-01-20 at 02:00.

For Debian 8 'Jessie', this problem has been fixed in version
2019a-0+deb8u1.

We recommend that you upgrade your tzdata packages.

NOTE: Tenable Network Security has extracted the preceding description
block directly from the DLA security advisory. Tenable has attempted
to automatically clean and format it as much as possible without
introducing additional issues."
