I have ESM 9.5 running but the system clock is set to use 'UTC' when I run 'date' on the ssh terminal. I tried to configure it to sync to my NTP server via System Properties but that does not change the OS clock time and timezone. Where in the system can I run the equivalent of 'ntpdate' command so that I can set the OS clock to use the timezone as my NTP server?
The ESM always stores time in GMT. Time configuration should be performed from the System Properties. Time can be displayed in any timezone on a per user basis. The setting is under Options on the top right of the GUI next to the username.
You generally want to think of the devices as a appliances and not a Linux device. There aren't any normal operating procedures that involve the shell.
