Sunset / sunrise give other values in dashboard then in debug window

Hi,
I'm new with node-red and I'm struggling with sunset / sunrise from openweathermap.
I getting sunset / sunrise from openweathermap and via a function node, I convert the epoch to a more readable format (just our date/time notation). These sunset / sunrise times are correct.
(the function node flows to the debug node) When I however display the same values (or so I think) in the dashboard, they give another time ??? (function node also flows to dashboard text) What is wrong here ??
The flow

The js Date is most likely UTC and Angular is formating a local timezone. Try messing with the timezone and local in the angular filter
https://angular.io/api/common/DatePipe#usage-example

Thanks for this fast reply, I'll try it out
