1970 really that is soo wrong??

this is what I’m getting:

So how do I fix this???

Still no answer?

It seems that the issue is tied with GZIP most servers have a CPANEL enter it and set the compression in there to see if anything changes.

I fixed it many months ago but I forget how I fixed it

I think I fixed in the web service .conf but I just can’t remember what I did.
