Event time not Updating

I have an event whose time was changed. The calendar on my website still shows the old time.

I have the refresh interval on all of my calendars set to 2 hours. I’m pretty sure the time was changed more than 2 hours ago since the office is not open yet today.

I cleared the cache for the Grouped calendar and the individual calendar. I also cleared my browser cache and duplicated the event with the updated time.

The event description is updated, but still not the time.
