The editing time of the file can be modified, but the modification time does not affect the security of the file. Nail is an enterprise-level office software. In order to ensure the security of documents, various security measures have been taken.

First of all, nail adopts end-to-end encryption technology to ensure the security of files during transmission. This means that the file will be encrypted during transmission, and only the sender and receiver can decrypt and view the contents of the file.

Secondly, nailing provides a strict authority control mechanism, and only authorized personnel can edit and modify files. Administrators can set different permission levels to restrict users' access to files and modify permissions, thus ensuring the confidentiality and integrity of files.

In addition, nailing also provides a version control function to record the modification history of files, including modification time, modifier and other information. Even if the modification time is changed, the administrator and the file owner can still get the real modification record of the file by viewing the version history.

To sum up, the editing time of the file can be modified, but this will not affect the security of the file. Nail has taken a variety of security measures to ensure the security of file transmission and access, and provided version control function to ensure the integrity and traceability of files.
