Timezones alignment across instance and reporting

[WYE]

TL;DR: Align timezones across reporting and web interface. 

Request:

When raised during our trial to engineering, the feedback is that browser displays local time, and reports are generated using UTC. 

The misalignment is visible in my example shown where a report shows a system was back online at 05:32:07, but it actually and factually came back online at 06:32:07. 

Suggest either including "UTC" in the report, or allowing time zones to be configured globally or per site. 

Also noticed, that the "Generated at 04 Sep 2020 01:20" footer on the report is 6 hours behind GMT (report generated 07:20am GMT), so this could also do with being aligned accordingly.
