            Enables X.509 certificate expiry checks in mbedTLS.

            If this option is disabled (default) then X.509 certificate
 | 
						|
            "valid from" and "valid to" timestamp fields are ignored.
 | 
						|
 | 
						|
            If this option is enabled, these fields are compared with the
 | 
						|
            current system date and time. The time is retrieved using the
 | 
						|
            standard time() and gmtime() functions. If the certificate is not
 | 
						|
            valid for the current system time then verification will fail with

 |

            Enabling this option requires adding functionality in the firmware
 | 
						|
            to set the system clock to a valid timestamp before using TLS. The
 | 
						|
            recommended way to do this is via ESP-IDF's SNTP functionality, but
 | 
						|
            any method can be used.

 | 
						|
            In the case where only a small number of certificates are trusted by
 |

            the device, please carefully consider the tradeoffs of enabling this
 | 
						|
            option. There may be undesired consequences, for example if all
 | 
						|
            trusted certificates expire while the device is offline and a TLS
 | 
						|
            connection is required to update. Or if an issue with the SNTP
 | 
						|
            server means that the system time is invalid for an extended period
 |

            after a reset.
