Wrong endDate when dragging events over days at which DST/STD change

Hi there,

I am having an issue regarding the days at which summertime switches to standard time and vice versa. I am using v4.3.6 of SchedulerPro with vue package. I am also working with Europe/Berlin timezone. To sync the scheduler changes I am using the change listener on the eventStore. Apparently, when moving an event (duration: 1 day, 00.00-00.00) onto the switch date, the new endDate is wrongly returned. E.g. when moving it from before 27.03.22 onto 27.03.22 the new end date is at 01.00 the next day, when moving it from after 30.10.22 onto 30.10.22 the new end date is at 23.00.

This can also be seen in the basic example on your website, if you do the same here, the event tooltip will show a wrong date also. https://bryntum.com/examples/examples-scheduler/basic/

While writing this I noticed there is a very similar issue here, maybe this is related: viewtopic.php?f=51&t=20331

Also, you might be aware, but it would be great if you could also add the fix to v5 as soon as it is there. Thanks for looking into it.

No news yet, but we will try to address this in 5.0.3.

Hi there, I saw that this ticket was closed, but I was able to reproduce it still in 5.0.4 as well as in your online examples like I mentioned in the original post. Can you please check that again?

Hey bdent,

We're considering fixing this in one of the 5.x.x patch releases. Thanks for asking.

Hello til.schniese
Could you please elaborate on your report? I am dragging events over the DST transition date in March and I am getting event at the dates which are displayed in the tooltip.
Could you maybe do a screen recording showing your problem on the online basic demo?
