Date & Time
Correctly set date and time is of greatest importance for the product to
operate properly. For instance, time scheduled policies and auto-update of
IDS signatures are two features that require the clock to be correctly set. In
addition, log messages are tagged with time stamps in order to point out
exactly when a specific event did occur. Not only does this assume a
working clock, but also that the clock is being synchronized with other
devices in the network.
To maintain current date and time, the product makes use of a built-in
real-time clock. The clock is also equipped with a backup battery to ensure
operation even if the product should have lost its power. In addition, the
product supports time synchronization protocols in order to automatically
adjust the clock based on information from other devices.
