Box's FTPS and SFTP options support the ability to preserve files' original created and modified date/timestamps during file transfers to Box. These timestamps are visible on Box to satisfy compliance or regulatory requirements. See Understanding Box File Timestamps
IMPORTANT: Most FTPS or SFTP clients support the ability to send a file's original modified timestamp during a transfer, however, most DO NOT support the ability to send both the original modified AND created date/time during a transfer. Consult with your FTPS or SFTP client's support team to confirm the available capabilities.
