End date is always +1 day after export to .ics file

[wie-was]

Steps to reproduce

1. Export a calendar

Expected behavior

Start and end dates of the exported .ics file match the entry in nextcloud calendar.

Actual behavior

The end date always seems to be 1 day off.

Example entry:

Exported ics file:

PRODID:-//IDN nextcloud.com//Calendar app 5.5.11+murena-20260107//EN
CALSCALE:GREGORIAN

DTEND;VALUE=DATE:19960721

What's your timezone set to? Check it in the settings modal.

Hi, thanks for the quick reply! If I get your question right, it's Europe/Zurich?

[tcitworld]

Thanks. Please note since Murena isn't providing the latest version of the app, this issue might have been fixed already.

[wie-was]

For sure. I searched for about 10 minutes to see if somebody already reported the problem, but I didn't find evidence. So I went ahead and opened a new issue. Apologies if this has already been reported/fixed.

I appreciate the hint that I could have something to do with the timezone setting.

Hi @wie-was

Can you tell us which version of NC and Calendar you are on?

[wie-was]

Hi @SebastianKrupinski, the NC version seems to have been bumped to 32 meanwhile (the issue persists, I did a quick check). However I don't think I'm able to tell the exact version of Calendar. I'm using the NC version of Murena Workspace at https://murena.io

This is all the info I get in the about section:
