Time format conversion

[E1cid]

@juntiedt

Sunrise and sunset comes in that format: "Sat Nov 25 2023 19:57:52 GMT+0100" and I need a timestamp of this format in oder to calculate the time difference. (duration of night and day for example).

You can do the calculation in the change node using moment().diff()
e.g.

   $moment($$.payload.sunrise).diff($moment($$.payload.sunset), "seconds")	

where msg.payload.sunset and sunrise are in format

{"sunset":"Sat Nov 25 2023 19:57:52 GMT+0100","sunrise":"Sun Nov 26 2023 07:57:52 GMT+0100"}

output in seconds

43200
