A thread waiting on a condition variable (a) can be explicitly notified and (b) may wake up before the time has expired (spurious wakeups). If you just want to sleep for a fixed amount of time, then sleep_for is the right tool.

My understanding is that sleep_for can wait more than the time wanted, right?

You can always wait longer than you ask for. A thread can wait even if you don't ask to wait. It's entirely dependent on the kernel's scheduling algorithm.

So basically a condition_variable can wait less, while sleep_for can wait a bit more?
