When I request 1 month of data, the hours are offset by one.
The data returned here will show it starting at 01:00 on the 1st and go until 00:00 on 02-01. Which is outside the date range.
When I select one day it will return the 23:00 but miss the 0:00.
Here for example the downloaded data will start at 01:00 and go till 1950-01-01 23:00. It misses the first hour.
