REST Api - creating issues with dates in the past

[acoder2020]

Is it possible to create an new issue in Mantis, but have it posted with an older date? I've looked through docs and haven't seen any reference to dates.

(for purposes of migrating old issue data from another system)

This is currently not possible.

I believe the XmlImportExport plugin can do this, but I have not used it in years so not 100% sure.
