Force created field, creating an issue via API

Hi everyone!

I tried to create an Issue VIA API, I created several without problem, but when I want to force the created field, I don't have luck. I tried with a long type,  timestamp in milliseconds like the documentation said and nothing, also I tried passing other type in created field such as object, string, to see if I found any problem, but the issue is created with the real date.

I'll be pleased if anyone can help me.
