Statistics-graph Card: X-axis legend offset by 12 hours?

I’m using the standard Statistics-graph card to display gas consumption. The data source is the total gas consumption reading from the gas meter, and I use the change displayed at hourly intervals for a period of 5 days.

However, the date legend shown on the x-axis appears to be offset by 12 hours, so for example the tooltip shown for the consumption reading at 16:00 on the 27th December appears as though it is at 04:00 on the 28th December. Am I doing something wrong here, or is this a bug? Thanks.

Could you elaborate?
A tooltip says “27.12 16:00”.
Why do you think it should be “28.12 04:00”?

No, you misunderstand - the tooltip shows the correct time/date of the consumption event, but it is placed on the graph at 04:00 on the 28th December. All the consumption events are shown shifted by 12 hours into the future.

I see, can observe a similar glitch:

Also, currently is 22:25, and the last part of the graph is wrongly horizontally scaled:

Each interval is 3 hours, so the last interval should be 00:00, although the graph comes almost to the right boundary.
