Import timestamps

[sargreal]

It would be really helpful to be able to include the created and updated timestamps in the import. Because when importing for example Articles from another CMS, one will probably want to include the time at which the article was created and updated. Using custom fields does not make so much sense since then the dates always need to be added manually.

I realize that this is currently not possible as strapi does not allow providing these on creation (AFAIK). Anyhow this issue should serve as a reminder that this should be implemented once strapi allows it.

A workaround with direct database manipulation might be possible but I'm quite sure that this is not best practice
