Description: System time at which device was initialized. For fixed devices, this will be the system time at boot up. For removable devices, it will be the time at which the device was inserted, which may be boot up time, or a later time (if device was inserted later). If a device (fixed or removable) was repartitioned, it will be the time of repartitioning. The purpose of this object is to help a management station determine if a removable device has been changed. The application should retrieve this object prior to any operation and compare with the previously retrieved value. Note that this time will not be real time but a running time maintained by the system. This running time starts from zero when the system boots up. For a removable device that has been removed, this value will be zero.
