For instance, the server's certificate will be considered as "long expired", or "not usable yet", leading to rejection. Accepting that the client's clock is off means that the client is modified to disregard dates … ssl - How much clock asynchronicity can secure protocols I've noticed that connections to a secure server got reset if time is out of sync on a server.
