Time Stamp
LTO: The Time Stamp is represented as number of power cycles and total
power on hours.
SDLT/DLT: Tape motion hours when check condition occurred (note that
this is the number of power-on hours since the last time the unit was
powered on, not total number of hours during the lifetime of the drive).
The time stamp counter is updated once per hour; if the tape drive is
powered down before the hourly update occurs, the update will not occur
until a full hour after power is reapplied.
