Ability to delete personal records

Based on this and this habratopik:

I would like to be able to delete personal records. And then several people already have dvuhzamkovye records that are not needed, but you can not delete them.

And for this comment :

The fact is that at the moment when you publish the saved text, it is marked with the date when you saved it, i.e. In fact, you publish an old topic, and it is not visible at all under a pile of new ones.

Can I set a new date?
