Description |

Select a time zone from the list. The default time zone is Pacific
Standard Time, displayed as Los Angeles, CA. When you configure a
time zone, PacketWise changes its local time automatically at the
start and end of daylight savings time. To configure a custom time
zone, see setup
timezone. |
| Date |
The current date setting. Update the date by entering a new value
in the format: mmm dd yyyy — for example, Dec 13 1999 |
| Time |
The current time setting. Update the time by entering a new value
in 24-hour format: hh:mm:ss — for example, 20:15:00 |
| SNTP Client |
PacketShapers are unicast Simple Network Time Protocol (SNTP)
clients, enabling them to synchronize clocks with a Network Time Protocol
server. Use this field to turn time synchronization on and off. Enabling
SNTP is especially useful when you are managing multiple Packeteer
units — all clocks will be synchronized, allowing more accurate
reconciliation of data when comparing reports and using a centralized
reporting tool.
Note: When time synchronization is enabled, the date and time
fields become read-only.
Occasionally, the default SNTP server intermittently reports that
it is unavailable or that a DNS error occurred. This can happen when
the default time server experiences downtime. |
| SNTP Poll Seconds |
The number of seconds between synchronization attempts. The default
is 300 seconds (5 minutes). |
| SNTP Primary |
The DNS name or IP address of the primary time server (the default
is time.nist.gov) |
| SNTP Secondary |
The DNS name or IP address of the secondary time server (the default
is time-a.nist.gov) |
