Scroll over the date/time in an Opportunity to see the current time zone:

If it is not the right time zone, follow these steps:

1. Go to Settings > Options in the top right corner

2.  Go to Set the time zone you are in and click the time zone to change it. When finished, click OK.

Now the dates and times should be correct throughout the CRM.
