_SvIncludePlusContent-_DP_Output
The data exported is the current snapshot of your instance (i.e. issues, custom fields, links, and users that exist at the time of export). You can find the exact time of the export in the names of the exported files or by checking the export details.
To access the export details:
Go to Administration > System > Data pipeline.
From the Export details list select Actions > View details.
3. You’ll find the export time in the exportFrom line.
If an issue or an issue link was permanently deleted, it won’t be found in these files. For all historical changes, you should consult the issue_history file.
The fromDate, which by default includes the last year, refers to querying for issues and their metadata updated since the supplied timestamp.
