How many seconds is a reboot in Fortnite?

I'm curious, how long does it typically take for a reboot to occur in the popular game Fortnite? I've heard players mention it, but I'm not entirely sure what the time frame is. Does the reboot process happen frequently, or is it more of a rare occurrence? I'm trying to understand the mechanics of the game better and how it affects gameplay. Could you provide a clear and concise answer to this question?
