how long is the timeout of a call to an external URL using PostURL()?

Hi people

I need your help ... I created a custom function for Zoho CRM that sends data from a client through a WebService to an SAP Server. For this I use the function postURL and it works well, but when I send Data too big, the function sends an error of "Time out: 'SocketTimeoutException'", so I need to know how long is the timeout of postURL function and if there is some way to control it.

Thank you.
