Nginx proxy_hide_header not worked at a field included whitespace

I have a proxy with nginx for a upstream.The upstream will return a invalid header :"Time : Tue Oct 18 11:24:50 CST 2022", This is the response headers.

HTTP/1.1 200 OK Server: nginx/1.21.0 Date: Sat, 01 Apr 2023 16:47:07 GMT Content-Type: text/html;charset=utf-8 Connection: keep-alive Cache-Control: no-cache Time : Tue Oct 18 11:24:50 CST 2022 

I need to remove the "Time " header.

location / { proxy_hide_header "Time "; proxy_pass server...; } 

But it dose not work.
