I have a single document that needs to exist in Google Docs and I want it to display my own creation and last-modified timestamps rather than the automatic ones. I will supply the exact dates and times for each field once we begin. What I need from you is a reliable way to embed those timestamps so that: • in Google Drive the “Created” and “Last modified” columns show my chosen dates You’re free to use whatever technique works—metadata editing tools, PowerShell, Python, Google Drive API, Office XML hacks—so long as the end result is two fully editable files reflecting the dates I provide. A short note on the steps you took will help me reproduce the process in the future. Absolute discretion is expected, as the documents are private.
