If you use Google Forms the chances are that your data will go to a Google Spreadsheet, which you can view at your leisure. Each time someone fills in the form a new record (row) is created in the spreadsheet and the time they did it is added in the timestamp column with the date.
Google defaults to American settings so will generally show US date format (month/day/year).
If you want to make it UK date format (day/month/year) do the following: Open the form, click on File, then Spreadsheet settings… then change ‘United States’ to ‘United Kingdom’ and click the blue Save settings button. The spreadsheet will refresh and the timestamps will now be UK style.
1. File / Spreadsheet settings…
2. Locale – change United States to United Kingdom, click Save settings.
3. What the setting looks like with United Kingdom (I got carried away taking screenshots).
