brew: Failed to set filetime 1503098583 on outfile: errno 1 I see now often a new error when invoking brew. It works anyway, but I wonder how to fix Failed to set filetime on outfile: errno 1

brew install redis

I had the same issue, and similar situation as others via Github Homebrew/brew #issue 2921.

It was the "remote-time" line from my ~/.curlrc file. 

To fix it, just comment out the line with a # like:

#remote-time
