I started a free trial at my-prtg.com. However, time and data values are displayed in American format. Where can I change this?
By default, PRTG uses the date format (and time zone) of the underlying Windows operating system. For PRTG Hosted Monitor instances, this is the American date format (and UTC time zone).
You can change the defaults in your user settings:
In the PRTG web interface, navigate to Setup | Account Settings | My Account. In the Web Interface section, select your preferred time zone and date format. Save your settings.
Note: This setting will only change the way data is displayed to you. Internally, PRTG will still use UTC time zone to store monitoring results.
