Upgraded. pre-existing calendar events shifted from local time to UTC

Bug

I ran ./laucher app rebuild this morning (there are other ways to upgrade too, like the GUI).

This is the current detail given on the Admin page.

My Discourse has a very active calendar. All the pre-defined event start and end times reset from local time to UTC. That has a significant impact on my community.

The image is a notification about an event titled "Operations 2024-12-22 rev.2," which occurred on December 22, 2024, from 2:00 PM to 10:30 PM. (Captioned by AI)

That event was defined as 9am → 5:30pm.

Can you show us the raw for that post where the event is defined?

Actually, the event is just displaying event times as UTC. Clicking (or perhaps hovering) the event shows this.

The image displays a calendar entry for December 22, 2024 with operations scheduled at various times in Toronto, Paris, and Los Angeles. (Captioned by AI)

Very weird. I’ve now seen a variety of cases:

  1. As another user, the event visited shows local time.
  2. As admin, an event was UTC. Refreshed. Event updated to local time.
  3. As admin, chose another event. Local time shown.
  4. As admin, that Dec 22 event still showing as UTC.
  5. As another user, that Dec 22 event displaying as local time.

I’m glad I have a screenshot or I’d think I was going crazy.

At a guess, these posts probably needed a rebake and your server is working through them and rebaking them with updated formatting.

On a post that still looks “wrong”, if you force a rebake:

A menu with options including Moderation History, Add Staff Color, Add Staff Notice, Change Ownership, Grant Badge, Lock Post, Make Wiki, Rebuild HTML, and Add User Note. (Captioned by AI)

does it look right?

I’m too late. I refreshed the page of my example and the event updated to local time.

If I find another problem event, I’ll try your suggestion.

I will add that my update was complete more than 5 hours ago. It’s not a big site. It’s also not a powerful server, but it is adequate.

This is a problem with local dates, sometimes they are not applied to the calendar, we are aware, I will try to fix this in the near future.

I can now confirm that a rebake did result in an update.

As admin, I found this event…

and then used the Rebuild HTML option and had this result…

The Rebuild HTML option doesn’t seem to be necessary. I can get a corrected result just by refreshing the page. It’s annoying though, because navigating from the Upcoming Events calendar to the event does give me the incorrect times. Members expect to see a reliable result every time.

I don’t think I’ve found a case of incorrectly displayed times for any user other than admin.
