CURLOPT_TIMEVALUE_LARGE explained
Name
CURLOPT_TIMEVALUE_LARGE - time value for conditional
Synopsis
#include <curl/curl.h> CURLcode curl_easy_setopt(CURL *handle, CURLOPT_TIMEVALUE_LARGE, curl_off_t val);
Description
Pass a curl_off_t 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.
The difference between this option and CURLOPT_TIMEVALUE is the type of the argument. On systems where 'long' is only 32 bits wide, this option has to be used to set dates beyond the year 2038.
