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(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.

DEFAULT

curl_easy_setopt(curl, CURLOPT_TIMEVALUE, 1577833200L);

/* If-Modified-Since the above time stamp */
