Purpose
This page will explain how to set the time that NMIS and OMK applications use to display data.
NMIS
NMIS will display data relative to the local system time of the server that it is running on. The best method of changing local time on the server varies based on the Operating System.
General Method
Find the desired timezone in the /usr/share/timezone directory.

### Confirm the current timezone [root@opmantek ~]# date Sat Apr 22 13:43:59 KST 2017 ### Remove current timezone config [root@opmantek ~]# rm -rf /etc/localtime ### Set to desired timezone [root@opmantek ~]# ln -s /usr/share/zoneinfo/UTC /etc/localtime ### Verify [root@opmantek ~]# date Sat Apr 22 04:46:29 UTC 2017 |
Debian Based Systems
Use the dpkg-reconfigure utility with the tzdata argument
...
This will launch a GUI in the terminal and guide the user through the process.

### Find the desired timezone [root@localhost ~]# timedatectl list-timezones ### Confirm current timezone [root@localhost ~]# date Sat Apr 22 01:05:47 EDT 2017 ### Change to desired timezone [root@localhost ~]# timedatectl set-timezone UTC ### Verify [root@localhost ~]# date Sat Apr 22 05:06:04 UTC 2017 |
OMK Applications
By default OMK applications will use the timezone that the server has been provisioned for. To change the time that OMK applications use to display data, opCommon.nmis needs to be udpated. Any timezone name declaration from one of the following sources may be selected.used:
- ISO 8601 TZ designators, e.g. "+10:00" or "+1000"
- TZ names from the Olson Database, e.g. "Europe/Paris".
- or the name 'local'
...
- the special value "
local
".
If the config item 'omkd_display_timezone
' is not present or blank, then the server timezone is used and times are shown without the timezone suffix.
If it is set to "local"
, then the server timezone is used but the applications show all times with the timezone suffix appended.
To adjust the timezone settting, edit conf/opCommon.nmis
and insert a key called 'omkd_display_timezone
' in the the omkd
section. Associate the desired timezone name with it as show below.

This method currently works for all OMK modules except Open-AudIT Enterprise.
