The imminent insertion of a leap second on June 30, 2015 has raised concerns about availability and reliability of computer systems. Utimaco has conducted an analysis of possible impacts of this leap second on our products. This analysis has led to the conclusion that handling of the leap second by CryptoServer HSMs and CryptoServer LAN appliances ensures valid system time settings. Neither degradation of service nor operational failure nor any security-relevant issues are to be expected.
