a. Correct the date and time using the date command where
<datetime> is a string of numbers representing the month, day,
hour, minute and second, for example
date 10061424.40 sets
the date to October 6, 2:24:40 pm:
date <datetime>
OR
b. If using an NTP server, use the
ntpdate command, where
<server> is the IP address of a contactable local NTP server:
ntpdate <server>
This command checks the NTP server time, and sets the local
server time (when run as root).
3. Login to the WebUI and check that the date/time is now being
correctly displayed as per the following example:
Fri Jan 17 01:39:30 GMT 2014 (before changing time zone)
Fri Jan 17 14:50:19 NZDT 2014 (after changing time zone)
The WebUI status bar shows the current time with UTC offset. For
example:
12:51:57 UTC+00:00 (the SCADA gateway local time is the
same as UTC)
12:51:57 UTC+13:00 (the SCADA gateway local time is 13
hours ahead of UTC)
4.7.2 Solaris
Note that only one local time can be used per network. All SCADA
gateways in a network must be set to the same time zone, regardless of
whether they are physically located in different time zones.
For first time installation and configuration the time zone can be set during
the installation of Solaris 10 (see the relevant section of Section 2.2
Installing the SCADA Gateway on the DMR Node Controller).
To change existing systems to a local time zone you must perform the
following procedure:
1. SSH to the SCADA gateway and execute the following as root:
a. Select the required time zone name from /usr/share/lib/
zoneinfo
b. Change the permissions of /etc/default/init so that it is
writable by root:
chmod 755 /etc/default/init
c. Edit the /etc/default/init file, so that a line starting with
TZ= has the timezone name you require, e.g.:
TZ=NZ
