I have a trend object which takes the time of the Raspberry Pi. In my project I take the time of the main board and now the time of the trend object, the date range selection and the time displayed on the screen are different. My question is how do I set the time of the trend and the date range selection that it matches the system time? And from where do this elements take the time?
One quick fix could be to set the time of the Raspberry Pi the same as the system time, but this does not explain that there were three different times.
