An attacker can change the plant time even when not authenticated in any way. This changes the system time possibly affecting lockout policies and random-number generators based on timestamps and makes timestamps for data analysis unreliable. NOTE: the vendor reports that this is largely irrelevant because it only affects log-entry timestamps and because the plant time would later be reset via NTP. (It has never been the case that a lockout policy or random-number generator was affected.) Also only Sunny Boy TLST-21 and TL-21 and Sunny Tripower TL-10 and TL-30 could potentially be affected.
