I have noticed that twtxt timestamps differ. For example:

• @prologic@twtxt.net (and I assume any Yarn user)
  2024-09-18T13:16:17Z
  
• @lyse@lyse.isobeef.org
  2024-09-17T21:15:00+02:00
  
• @aelaraji@aelaraji.com (and @movq@www.uninformativ.de, and me)
  2024-09-18T05:43:13+00:00
  

So, which is right, or best?

@quark@ferengi.one They’re all RFC3339, unless I’m mistaken: https://ijmacd.github.io/rfc3339-iso8601/ So they’re all correct.

@quark@ferengi.one @movq@www.uninformativ.de Yep, they’re all RFC3339. Obviously, +02:00 and +01:00 are best, because I use them! :-P In all seriousness, Z might be the best timezone, as it is shortest. And regarding privacy, it leaks the least information about the user’s rough location. But of course, one can just look at the activity and narrow down plausible regions, so that’s a weak argument.
