No time source
Summer time starts 02:00:00 CST Sun Apr 7 2004
Summer time ends 02:00:00 CDT Sun Oct 27 2004
This indicates that no time source is configured.
Manually Setting the System Clock
Use the
clock set
hh:mm [:ss] month day year
command to manually set the clock on the appliance. Use
this command if no other time sources are available.
Note
You do not need to set the system clock if your sensor is synchronized by a valid outside timing
mechanism such as an NTP clock source.
For the procedure for configuring NTP, see
Configuring NTP, page 4-27
. See
Time Sources and the
Sensor, page 4-18
, for an explanation of the importance of having a valid time source for the sensor. For
an explanation of what to do if you set the clock incorrectly, see
Correcting Time on the Sensor,
page 4-20
.
The
clock set
command does not apply to the following platforms:
•
IDSM-2
•
NM-CIDS
•
AIP-SSM-10
•
AIP-SSM-20
To manually set the clock on the appliance, follow these steps:
Step 1
Log in to the CLI using an account with administrator privileges.
Step 2
Set the clock manually:
sensor#
clock set 13:21 July 29 2004
Note
The time format is 24-hour time.
Configuring Summertime Settings
You can configure summertime settings if you did not do so during initialization of the sensor. Or you
can change them after initialization.
Note
Summertime is a term for daylight saving time.
