Cards not showing time in BST

Although the time at the top of the portal "menu" on L/H side is correct for BST, the time shown on the power graph and weather forecast cards is still showing as GMT, which although I can make the mental adjustment ok, is annoying, and also makes reports incorrect; e.g. the first hour of this morning's EV charge which started at 00:30 BST was included in the report for yesterday. Is there a way to adjust this in settings, or is it a bug in the new portal version which needs fixing?

Whilst waiting for my installation date, I have been checking out the demo on the cloud portal, and looked at the power graph with the addition of the 'PV Generation Energy Today'.
What surprised me was the step change from 5.2 kWh to 0 kWh took place at an indicated 01:00.
I presume the energy total from yesterday was 5.2 kWh, which was then reset to 0 kWh at 00:00 GMT, but shows on the graph at 01:00 BST.
Does this also apply to daily totals, so historical values may not match with other metering systems such as smart meter reports due to the 1 hour time offset?
