CURLOPT_TIMEVALUE explained

Name

CURLOPT_TIMEVALUE - time value for conditional

Synopsis

#include <curl/curl.h>
 
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_TIMEVALUE, long val);

Description

Pass a long val as parameter. This should be the time counted as seconds since 1 Jan 1970, and the time is used in a condition as specified with CURLOPT_TIMECONDITION.

On systems with 32-bit 'long' variables (such as Windows), this option cannot set dates beyond the year 2038. Consider CURLOPT_TIMEVALUE_LARGE instead.
