Change server timezone

You can manage timezone using one simple command: timedatectl

First, view current settings:

 1[otsmanager@server ~]# sudo timedatectl 
 2      Local time: Sun 2015-12-27 01:31:46 UTC
 3  Universal time: Sun 2015-12-27 01:31:46 UTC
 4        RTC time: n/a
 5       Time zone: UTC (UTC, +0000)
 6 Network time on: no
 7NTP synchronized: yes
 8 RTC in local TZ: no

If necessary, change the timezone:

 1sudo timedatectl set-timezone America/New_York

If you want to know what time zones are available, execute:

 1sudo timedatectl list-timezones
