# NAME
CURLOPT_TIMEVALUE - time value for conditional
# SYNOPSIS
~~~c
#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(3).
On systems with 32 bit 'long' variables (such as Windows), this option cannot
set dates beyond the year 2038. Consider CURLOPT_TIMEVALUE_LARGE(3)
instead.

int main(void)
{
CURL *curl = curl_easy_init();
if(curl) {
curl_easy_setopt(curl, CURLOPT_URL, "https://example.com");
/* January 1, 2020 is 1577833200 */
curl_easy_setopt(curl, CURLOPT_TIMEVALUE, 1577833200L);
/* If-Modified-Since the above time stamp */
curl_easy_setopt(curl, CURLOPT_TIMECONDITION, CURL_TIMECOND_IFMODSINCE);
/* Perform the request */
curl_easy_perform(curl);
}
