The instant kill time could be a few seconds, a few minutes, a few hours, or even longer. The specific instant kill time depended on different platforms and event settings. On e-commerce platforms such as Amazon and Jingdong, the instant kill time was usually a few hours, but on shopping sites such as Taobao, the instant kill time might only be a few seconds. Therefore, the specific time of the instant kill could be determined according to different situations. There was no fixed time limit.
It really varies. A short story might only last a few minutes, so that could be a few hundred seconds. But a longer one could go on for hours and be tens of thousands of seconds.
Well, there's no set number. It depends on the genre, style, and purpose of the story. A news story might be 30 seconds, while a bedtime story could last 300 seconds or more.
Instagram stories are typically 15 seconds long. However, if you use some special features or editing tools, you might be able to extend the duration slightly.
