In my setup the posts ase saved using this slug:
slug: "{{year}}-{{month}}-{{day}}-{{hour}}-{{minute}}-{{second}}"
In Decap cms I get files which are using UTC timezone, but it seems that Sveltia is now using local timezone. This now causes for me other issues as the website code expects the times in urls to be specified in UTC.
I don't think I previously had the some problem even with Sveltia, so has something related to this changed in Sveltia?
