I need to have a https server running on the ESP8266 to have a RESP API running over TLS (using bidirectional authentication), but I am facing an issue with the current SSL library from ESP, and it is that to check the certificates it needs to get the time from a SNTP server. Unfortunately the ESP8266 won't have internet access and there is no guarantee that there will be a SNTP server available in the local network.
Do you know of any other TLS library available for the ESP8266 (non os sdk) or a way I could somehow provide the time rather than get the time from and SNTP server?
Any help is much appreciated.
