System Dates are timestamps—representing the date and time of an entry’s creation— that are auto-generated for all content entries in a Symphony project. System dates are not visible while creating or editing entries, but are available to data sources for sorting and output.


System dates are auto-generated upon entry creation and are not editable.

Unlike system IDs, system dates cannot be used for data source filtering and are not included in an entry’s XML output. They can populate data source output parameters, but their primary use is in sorting a data source’s result set.
