IsOneDayEvent logic fails during DST fallback. Start date - End date is 25 hours
Example
Start Date: Sun Nov 02 2025 00:00:00 GMT-0600 (Mountain Daylight Time)
End Date: Sun Nov 02 2025 23:59:59 GMT-0700 (Mountain Standard Time)
The internal logic isonedayevent dictates anything greater than 24 hours is multi day, but it fails to account for this scenario.

Hello,
This appears to be a Scheduler issue related to Daylight Saving Time (DST). Since the Scheduler relies on the JavaScript Date object, it cannot fully handle DST time shifts, which may lead to incorrect date calculations in certain timezones on specific DST transition dates. The development team is aware of this problem and is considering a fix for future releases; however, there is currently no estimated timeline.
Unfortunately, at this time, there is no any workarounds.
