System Time
You can manually set the system date or time or have the security appliance dynamically set the system
date and tim e using an NTP server.
See the following topics for more information:
• Clock, page 6-2

Clock
The Clock pane lets you manually set the date and time for the security appliance. The time displays in
the status bar at the bottom of the main ASDM pane.
In multiple context mode, you can set the time in the system configuration only.
To dynamically set the time using an NTP server, see the NTP pane; time derived from an NTP server
overrides any time set manually in the Clock pane.
