(Node.js) FTP Set Remote File Date/Time Equal to Local File's Last-Modified Date/Time

Demonstrates how to set a remote file's date/time to be equal to a local file's date/time.

Important: Not all FTP servers support the ability to set a file's date/time.

Note: This example requires Chilkat v11.0.0 or greater.

Install Chilkat for Node.js and Electron using npm at Chilkat npm packages for Node.js Chilkat npm packages for Electron on Windows, Linux, MacOS
