Go to Reports Settings
From your HubSpot Dashboard, navigate to Reports > Reports Settings.
Choose your time zone
Scroll down to the Time Zone section and select your time zone from the dropdown menu. The options are broken down by regions (US, Europe, etc). Click the Save button.
Please note: regional time zones (e.g. US/Eastern) will adjust for Daylight Savings Time, if applicable. Time zone options that do not include a specific region/location will not adjust for Daylight Savings (e.g. EST).
