Timeout of IOC and FOK orders

What’s the time limit of IOC and FOK orders? I’m placing IOC orders and even with a wait of 5 secs or more they still show as pending? That’s not really what I would call ‘immediate’. Messes up my entire order logic when I get a surprise fill later that doesn’t have a position closing order in place. It feels like a really wishy-washy grey area where these are just soft limit orders.
