 To configure the daylight saving settings:

Last Attempt Status Specifies the status of the last SNTP request or unsolicited message for both 
unicast and broadcast modes. If no message has been received from a 
server, a status of Other is displayed. These values are appropriate for all 
operational modes:
•  Other. The status of the last request is unknown, or no SNTP responses 
have been received.
•  Success. The SNTP operation was successful, and the system time was 
updated.
•  Request Timed Out. After an SNTP request was sent to an SNTP server, 
the response timer expired before a response from the server was 
received.
•  Bad Date Encoded. The time provided by the SNTP server is not valid.
•  Version Not Supported. The SNTP version supported by the server is not 
compatible with the version supported by the client.
•  Server Unsynchronized. The SNTP server is not synchronized with its 
peers. This is indicated by the leap indicator field on the SNTP message.
•  Server Kiss Of Death. The SNTP server indicated that no further queries 
were to be sent to this server. This is indicated by a stratum field equal to 
0 in a message received from a server.
Requests Specifies the number of SNTP requests made to this server since the last 
reboot.
Failed Requests Specifies the number of failed SNTP requests made to this server since the 
last reboot.
