I have a question about openweathermap’s rain forecast

It provides forecast for next “3”, “6”, “9”, “12”, “15”, “18”, “21”, “24” hours. Each of these has a rain forecast in mm. What is not totally clear is if these forecasts are just for the amount of rain that is going to fall between 0-3 hours, 3-6 hours 6-9 hours etc from now, or would for example the 9 hour forecast include 0-9 hours?

I looked at the openhab openweathermap page and it doesn’t seem to specify. I also looked at the openweathermap docs and they also don’t seem to specify.

Does anyone know how this works?

Have a look at what the API returns.
It returns the results for 3 hour intervals and the start time of the specific interval thus it must be the amount of rain for that specific 3 hour interval that starts at the specific time.
