Timeline in History screen is not Always correct

[francoisqueru35]

In the history screen, while switching scale, the timeline is not correct for 6 and 12 hours.
For 6 : the current hour appears two times (see screenshots attached)
For 12 hours : the graph is one hour wrong (i.e 7 instead of 8 on the screenshots

Any idea why?
