Audit trail

Each time you change the value of a data item, an audit trail records the date and time of the change, the user name of the person making the change, and the reason for the change. You can review the audit trail of an item in several ways:

On the Data Value(s) page—Select a change date and time from the Audit Trail list.
The details of the change appear in the Reason for Change section.
On the Data Value(s) page—Click the Audit Trail tab.
On the form—Click the audit trail icon for the item whose audit trail you want to view.

Audit trail date/time conversion

The time (Date hour:min:sec) at which you enter data into the InForm application is stored in the InForm database in GMT (Greenwich Mean Time). However, the time that displays in the InForm audit trail depends on the time zone you specify for a site. You specify the time zone for a site through processing of the Site MedML, or by selecting a Time Zone on the Site's detail page when creating a site through the InForm Admin interface.

Valid time zone values must match those provided by Microsoft in the registry for your operating system. In addition to the list of time zone names, Microsoft stores each time zone's offset from GMT and details on the start and end date/time of daylight saving time where applicable. The InForm application uses this information to convert the data entry date/time stamp to the time zone for the site.

The InForm application:

Reads the audit date/time stamp from the database.
Retrieves the site's time zone setting specified in the InForm metadata.
Looks up the site time zone in the operating system registry, returns the necessary offset information, and determines whether the date/time in question in within or outside the daylight saving time adjustment.
Converts the date/time stamp from the database according to the offset information and displays the converted information in the audit trail in the user interface.
