In Collector, I can create a date field so when field users collect a feature, they can enter a date. Is there a way to automate this process, so today's date is entered automatically as an attribute for each feature that is collected?
If you enable edit tracking for the feature, several fields will be created and automatically updated - Creation Date, Creator, EditDate and Editor. When your users collect a feature, the EditDate will show the time (usually in UTC) the feature was last edited and who the user was that did the edit.
Thank you for the helpful information. Good to know that "Creator and Editor" are tracked too.
Previously I was just using the GNSS Metadata - ESRIGNSS_FixDateTime filed name.
A clarification. As I mentioned, with ArcGIS Online the time is typically stored as UTC. However, Collector or a web browser will use its settings to display the time/date as local time. If you download the data as a file geodatabase, you may need to do a time conversion to get local time.
