Bad time label
As you can see in the attached screenshot, `00` is visible as timestamp on the x axis. I guess it should be `23:30`.
Is it UTC? It would be better to visualize charts according to the timezone of the phone.
The time is in UTC timezone, but it is a displaying bug, thank you for reporting. Also, what is the type of the phone (for reproducing the bug)?
It is Nokia 6.1 (2018) with stock Android 10.
