In order for alerts to work properly, you will need to set your Metric Insights server to the same timezone as your data source. (If that is not possible, please contact us for assistance.)

DEFAULT_TIMEZONE is now set from /etc/mi/insight.conf. It does not need to be modified in const.php or config_variable, anymore. It may come a time where we want users to be able to set the timezone from the web UI. For now, however, that is not possible.

For now, a customer can set the timezone either by manually editing insight.conf,

OR

by running `mi-db-mgr timezone <tz_name>`.

The last method should be used as it takes care of modifying /etc/localtime as well as sets the timezone on boot.
