CURL set date via php - php

Question

i have been searching around for awhile without any luck.
im wondering if it is possible to set the date of a server with curl()?
i currently got this code to login and retrive data
$ch = curl_init();
curl_setopt ($ch, CURLOPT_URL, $loginURL);
curl_setopt ($ch, CURLOPT_SSL_VERIFYPEER, FALSE);
curl_setopt ($ch, CURLOPT_USERAGENT, "Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.1.6) Gecko/20070725 Firefox/2.0.0.6");
curl_setopt ($ch, CURLOPT_TIMEOUT, 60);
curl_setopt ($ch, CURLOPT_FOLLOWLOCATION, 1);
curl_setopt ($ch, CURLOPT_RETURNTRANSFER, TRUE);
curl_setopt ($ch, CURLOPT_COOKIEJAR, $cookieFile);
curl_setopt ($ch, CURLOPT_COOKIEFILE, $cookieFile);
curl_setopt ($ch, CURLOPT_REFERER, $loginURL);
curl_setopt ($ch, CURLOPT_POSTFIELDS, $postData);
curl_setopt ($ch, CURLOPT_POST, 1);
But sometimes i the server im getting data from, to think that it is another date.
i know i can mane another curl "partion" to get data from at specifik date by the url, but i figure it is faster to only call the remote server once, so if it is possible to set a header or something?
I specific wonna do this: trick the server, that i call via CURL to think that it is to days in the future

You should have a detailed look at the:
PHP.net setopt Manual
With curl, you can set a full header with curl_setopt($handle, CURLOPT_HTTPHEADER, $header).
I don't entirely understand what you are attempting to in your specific case but hopefully this example might be useful:
$agent = 'Mozilla/5.0 (Windows; U; MSIE 7.0; Windows NT 6.0; en-US)';
$header[0] = "Accept: text/xml,application/xml,application/xhtml+xml,";
$header[0] .= "text/html;q=0.9,text/plain;q=0.8,image/png,*/*;q=0.5";
$header[] = "Cache-Control: max-age=0";
$header[] = "Connection: keep-alive";
$header[] = "Keep-Alive: 300";
$header[] = "Accept-Charset: ISO-8859-1,utf-8;q=0.7,*;q=0.7";
$header[] = "Accept-Language: en-us,en;q=0.5";
$header[] = "Pragma: ";
$ch = curl_init();
curl_setopt ($ch, CURLOPT_URL, $url);
curl_setopt($ch,CURLOPT_USERAGENT, $agent);//s[array_rand($agents)]);
curl_setopt ($ch, CURLOPT_HTTPHEADER, $header);
curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt ($ch, CURLOPT_CONNECTTIMEOUT, 0);
$fileContents = curl_exec($ch);
curl_close($ch);
Further, if you are working with multiple curl requests you might consider a great library written by Josh Frasier, called Rolling_Curl.
