How to Change the Form Timezone
All form responses received in the Google Spreadsheet have a timestamp associated with them. If the time of the form response is different than your local time, it is likely that that timezone of your spreadsheet is not correctly setup.
To fix the timezone, open your Google sheet, go to the File Menu and choose Spreadsheet settings.
Choose the correct time zone from the list and click the Save Settings
button to apply the new timezone to your File Upload Forms.
