The Heart of the Controller (also known as the Heart) holds a backup of the system
which can be used to:
Clone the system onto a replacement CPU Card if the original requires
replacement.
Return the system to an earlier state.
All aspects of the system are recorded in the backup including firmware, learnt lamp
loads, fault logs, configuration and all handset / web page changes made prior to the
point at which the backup was taken.
The Heart is implemented using an SD card fitted to the CPU Card.
Backups are created and written to the Heart periodically, usually at 00:30am but this
can be changed if required. Backups can also be created and saved on demand using
the 'Controller – Heart – Backup & Restore' web page; the User Interface Handbook
667/HU/46000/000 contains more information.

The controller maintains two time references: Controller Time and System Time. The
relationship between these two times depends on the Time Mode selected: the times
may be locked together or run independently. The Time Mode is set to match the use
of the controller e.g. stand alone (Controller Time).
System Time is used for:
System log time stamps
Site log time stamps
Time of day in GVP applications (e.g. UTMC OTU)
Controller Time is used for:
CLF
Security classification
