How to update/install zoneinfo timezone database on CentOS?
Solution 1:
Don't update the zoneinfo database manually. Just install the updates which are already provided for you by EL/CentOS in the tzdata
package:
# yum update tzdata
Also note that MySQL keeps its own internal time zone tables, separate from the system timezone database. To update MySQL's internal time zone tables, run the mysql_tzinfo_to_sql
script which came with MySQL.
