Todt format in schedule.xml is out of bounds

Please note in the below the crazy formatted todt in the schedule we are getting after an upgrade to 1.8.10. Can someone explain how to fix this? I’ve checked all the regional settings and all the CMS/display settings I can think of. This occurs whether using a default schedule or a set schedule (say 8 hours).

The error on the client side log is:

Unable to load schedule from disk: String was not recognized as a valid DateTime

I certainly did not see this issue in 1.8.10, are both CMS and player in that version?

Does that happen with new events created after upgrade or is that an event that was there before upgrade?

What is the actual toDt of that event in CMS please?

Client and CMS at 1.8.10
Happens with any event including default layout for both new and old events.
The specific one it was happening with that was most concerning was the default layout. We normally don’t have many scheduled events and the default was producing that

It’s our Display Group
For whatever reason this was causing the issue
Deleted and recreated and things are normal now. I could definitely trigger it by add/removing displays from the group and the would break with the schedule error

That’s really odd, unless you had some event scheduled to that group with somehow very odd toDt, as that would then affect all displays that are part of that group.

We’d need to see the CMS and/or logs to tell what was wrong there really.

In any case, I’m glad that it works correctly for you now.
