The current local date and time for the system.
Setting this object is equivalent to setting an automated
clock and calendar. The value of the object will track the
date and time from the value set. Note that due to hardware
limitations some systems may not be able to preserve such
meaning across reboots of the system, as indicated by
csyClockLostOnReboot.
A constant value of all zeros and length 8 indicates the
system is not aware of the present date and time.
This object may be read-only on some systems.
