As you can see in the lzip manual[1], the lzip format does not contain neither the name nor the modification time of the input file, so that identical input will lead to identical output. Lzip compression is reproducible.

But if you need these data, you may append them as metadata to the compressed file and manage them with lziprecover[2].
