boottime -- System Administration File that holds time system was last booted /etc/boottime is an empty file maintained by the init process and the date command. The modification time of boottime, as displayed by the command ls -l, is the time that the system was last booted. You can read the time shown by boottime with ls -l, or with the system calls stat or fstat. Files /etc/boottime See Also Administering COHERENT, date, init, mount Notes Commands that depend upon /etc/boottime may malfunction if the system's date is not set correctly. For instance, the mount command depends on the relative modification times of /etc/boottime and /etc/mtab to detect whether the mount table has been invalidated by a system boot. If the date is set sufficiently far into the past, the mount table may appear to be valid when in fact it is not.
