Calendar Date Wrong

[HerrMann]

Anyone noticed this issue in El Capitan? Since the update, the calendar date in the Dock is not changing at midnight to the next day. The calendar states it is October 1st, but the Dock icon shows September 30th.

Okay, so it just ticked over to Oct. 1st. I am in the Mountain Time zone, which is one hour ahead of Cupertino. It seems as if the Calendar is calibrated to switch over at midnight pacific time.

Is there a way to change this?

Has no one else experienced this?

Noticed this problem since ios8. Times for appointments in Calendar arbitrarily changed for timezone Cupertino even though specifically the time zone was set for Denver and Time Zone Override is set to Denver. I notice this when I have looked at future events and find (pdt) in the time display and on notifications. Apple Support has, so far, been unable to answer why..
