Setting TimeOut in CURL using PHP

I've searched a lot about setting time out for curl request in PHP, but none seems to be helpful. I'm using CURL-7.15.5 version. I'm trying to set time-out for a request in milliseconds. I know that in curl-7.16.* there is new option CURLOPT_TIMEOUT_MS, which can set time out in milliseconds. Is there any way to user CURLOPT_TIMEOUT (7.15.5 style) to setup time-out less than a minute?

Any pointers will be appreciated.
