Re: Curl timeout option in milliseconds

Hi Daniel,

Please find the below logs from our application testing.

Cases 1, 2 and 3 work fine but timeout occurs wrongly in cases 4 and 5.

Please correct me if my understanding here is wrong.

*Note : *Time is printed in our logs in UTC time and in T date time format
– YYYY-MM-DDTHH:MM:SS.ssssss

Case 1

CURLOPT_TIMEOUT_MS = 1000 milliseconds

Setting CURLOPT_TIMEOUT_MS to 1000 milliseconds
