Google Calendar Invites Appear in UTC Time Zone

One of my users receives Google calendar invites in UTC time zone in the subject line of the email invites he receives in Outlook.  I sent a test invite to myself from one of my Gmail accounts to my Outlook (same domain and time zone as this other user) and the subject line's event time is the same as the actual event time (correct time and time zone).  When I sent the same invite to this other user, it shows up in the subject line in UTC time zone (test event was scheduled for 1 pm to 1:30 pm Central and shows up labeled as 6 pm to 6:30 pm (UTC) )  When accepted, the event goes into his Outlook calendar with the correct time.  What do I need to change to get these invites to show up correctly in the subject header?  This is a higher up in my company and he receives all of his invites for his charity he runs via Google calendar invites.
