To change the time zone that is used in your Hopscotch dashboard:
First, click Admin Settings in the top right drop-down menu of your dashboard.
Next, scroll to the middle of the page and select the Time zone you would like to use.
Finally, click on the Save Settings button at the bottom of the screen.
The only exception is with Smart Queue posts and Recurring posts. The Smart Queue lists and Recurring lists use the time zone that you set in their list settings in the Hopscotch dashboard.
