This should be the time counted as seconds since 1 Jan 1970, and the time is used in a condition as specified with \fICURLOPT_TIMECONDITION(3)\fP. On systems with 32 bit 'long' variables (such as Windows), this option cannot set dates beyond the year 2038. Consider \fICURLOPT_TIMEVALUE_LARGE(3)\fP instead. .SH DEFAULT 0 .SH PROTOCOLS HTTP, FTP, RTSP, and FILE .SH EXAMPLE .nf 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); } } .fi .SH AVAILABILITY Always .SH RETURN VALUE Returns CURLE_OK .SH "SEE ALSO" .BR CURLOPT_TIMECONDITION (3), .BR CURLOPT_TIMEVALUE_LARGE (3)
