 iPXE uses the time and date primarily for validating [[:​crypto|X.509 certificates]]. ​ If your system clock is inaccurate, then iPXE may erroneously decide that a valid certificate has expired. ​ You can use the ''​ntp''​ command to work around this problem, by fetching the time and date from an external NTP server. ​ You should be aware that there is no security or authentication used for NTP, and so using the ''​ntp''​ command is effectively equivalent to ignoring the validity period of any X.509 certificates. iPXE uses the time and date primarily for validating [[:​crypto|X.509 certificates]]. ​ If your system clock is inaccurate, then iPXE may erroneously decide that a valid certificate has expired. ​ You can use the ''​ntp''​ command to work around this problem, by fetching the time and date from an external NTP server. ​ You should be aware that there is no security or authentication used for NTP, and so using the ''​ntp''​ command is effectively equivalent to ignoring the validity period of any X.509 certificates.
