Data center clusters needs accuracy of microsecond operating in Time Domain and system virtualization. Chronology of LOG events is important for investigating error logic. Time & date is essential for automatic night backups requiring accuracy of milisseconds.
Weak synchronization of clusters keep risk of data base transactions to be not completed in time and volatiling full system backup. Frequently synchronization problems volatile Data Center cyber-security too.
