With the Temporal API will all of the browsers / nodejs etc be able to get the time right when performing operations around that time or will they need to be updated in order to not mess up calculations?
I also started on spacemacs but then I wanted to learn the basics of it and switched to writing my own configuration from scratch.
What helped me the most is reading though the Mastering Emacs book by Mickey Petersen which is an amazing resource to learn the basics and beyond.
Right now I'm in the process of reducing the number of external packages I use and I'm trying to use more of the built in functionality that is available "out of the box".
