I just released my new plugin, obsidian-date-in-metadata that automatically insert date and time on file creation (regardless of the trigger, from a link, a keyboard shortcut, or whatever…).
I don’t know if such a feature already exists, I don’t think so (I’ve already searched a lot).
But here it is, it solves a problem I had for a long time (I’m on linux, so no creation date for my files…)
I’ve been using Update Time on Edit for ages. It will make sure the file creation date is placed in the YAML and will also update the last date edited.
