Questions: BMC Clock Skew - Certificate Failure

• What is the current date/time on the BMC, and how far off is it from actual time?
• Does the BMC have NTP configured, and is it able to reach the NTP server?
• Did the BMC clock drift or reset because the server was powered off for 3 weeks?
• What are the validity dates on the BMC's SSL certificate?
• Is the BMC battery (which maintains the RTC) functioning?
• Can the BMC clock be set manually via ipmitool or the iLO CLI?
• Would regenerating the self-signed certificate fix the issue, or is the clock the root cause?
• Are other BMCs that were powered off during the same maintenance window affected?
• Can monitoring scripts be temporarily configured to skip certificate validation?
