FW: Time Date on file

I have address the following question to github support and the refer me to git documentation but I`m not too familiar with Git right now.  Here`s my question:

I did not find any config, but is there one configuration somewhere to preserve the real date creation by author somewhere?

Thanks in advance,

Hi there,

Not that I'm aware of, however this would be something specific to Git, not just GitHub. You'd need to check the Git documentation.

Thanks, James
