We found the the calendar cannot show correct date and time of an event after update. please see our link, 4 March event should be single day from 3pm to 6pm, but the calendar shown over 2 days.
And also we found that from the event editing page, the “ticket sell until” time cannot be set properly at a time before the event ends. In the 4 March event, the sell until time can only be set at 5 March 7am. Seems it is not complying with the WP locale time. Our time zone is UTC+8.
