• Primary Server: The IP address of an SNTP or NTP time server that the access
point attempts to poll for a time update.
• Secondary Server: The IP address of a secondary SNTP or NTP time server. The
access point first attempts to update the time from the primary server; if this fails it
attempts an update from the secondary server.
Note: The access point also allows you to disable SNTP and set the system clock
manually.
Set Time Zone – SNTP uses Coordinated Universal Time (or UTC, formerly
Greenwich Mean Time, or GMT) based on the time at the Earth’s prime meridian,
zero degrees longitude. To display a time corresponding to your local time, you must
indicate the number of hours your time zone is located before (east) or after (west)
UTC.
Enable Daylight Saving – The access point provides a way to automatically adjust
the system clock for Daylight Savings Time changes. To use this feature you must
define the month and date to begin and to end the change from standard time.
During this period the system clock is set back by one hour.
CLI Commands for SNTP – To enable SNTP support on the access point, from the
global configuration mode specify SNTP server IP addresses using the sntp-server
ip command, then use the sntp-server enable command to enable the service. Use
the sntp-server timezone command to set the time zone for your location, and the
sntp-server daylight-saving command to set daylight savings. To view the current
SNTP settings, use the show sntp command.
