CURLOPT\_TIMEVALUE(3) Library Functions Manual CURLOPT\_TIMEVALUE(3)

# [NAME](#NAME)

CURLOPT\_TIMEVALUE - time value for conditional

# [SYNOPSIS](#SYNOPSIS)

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

# [DESCRIPTION](#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)*](/man/os/curl/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)*](/man/os/curl/CURLOPT_TIMEVALUE_LARGE.3) instead.

int main(void)
{


  CURL *curl = curl_easy_init();

    /* 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 */


    result = curl_easy_perform(curl);


    curl_easy_cleanup(curl);


  }
}
```

# [HISTORY](#HISTORY)

**CURL\_TIMECOND\_*** enums became *long* types in 8.13.0, prior to this version a *long* cast was necessary when passed to [*curl\_easy\_setopt(3)*](/man/os/curl/curl_easy_setopt.3).
