I have a related but different take on this. I have an offgrid install where I am more interested in setting system time up so that the reports consider my "day" to start at 7am as 00:00 in the data. My real time is -7 GMT (mountain standard time in US). Can I accomplish what I want by setting "system time" to 0 GMT, or would it be +7 GMT ?
and.... when would it show up in the monitoring/reports ?
or, do I leave the system set to -7GMT, and set the time in the clock setting ?
