The various email activity heat grid reports are based on the time in CST. So for example, if someone clicks the link at 9:00 AM EST, the heat grid report would show the click at 8:00 AM CST. But what if they click a link at 9:00 AM EDT (Daylight Saving Time)? Is the click shown at 8:00 AM (CDT) or at 7:00 AM (CST) in the heat grid? And what happens when the report date range includes clicks that occured in both Standard and Daylight Time?
