Clock is Unsynchronized. The clock is unsynchronized issue occurs when the NTP master does not authenticate the NTP client request. This type of issue can occur when the authentication-key and password are not configured on the master end. This clock unsynchronization can be confirmed with the output of the show ntp status and show ntp ...

A stratum of 16 is unsynchronized and said to be insane. A level 16 stratum device is not a valid time source. NTP typically sends time in Coordinated Universal Time (also known as Universal Time Coordinated or UTC). Adjustment for local time can be done on the local time server or on the client device.
Protocols that do this include the topic of this book, the Network Time Protocol (NTP) [3], as well as the Digital Time Synchronization Service (DTSS) [4] protocol and others found in the literature. Simply stated, NTP is a distributed service that synchronizes the computer clock to an ensemble of sources, either remote via the Internet or ...
Network Time Protocol (NTP) is a protocol used to synchronise computer /Network time clock in a network.It belongs to TCP/IP protocol suite.The term NTP applies to both the protocol and the client-server programs that run on computers or servers.

Mar 13, 2013 · The exit onion router records the circuit ID, the destination IP address, the port number, and timestamp. The entry router records the timestamp of manipulation, the circuit ID, and the source IP address. We use Network Time Protocol (NTP) to synchronize the malicious entry and onion routers.

By creating Cisco-like CLI, Mellanox inherited classic IOS problems: lack of rollback, configuration management, filtering options and other things (100 things why we love Juniper). Later, XML API was introduced - but it still looks like a wrap of old CLI commands (why not do Netconf?).
OWAMP uses NTP-specific system calls to fetch time and time error estimates from the system kernel if they are available. It will report the time as unsynchronized if it is unable to access the NTP information this way. (It is still possible that the system clock is synchronized, OWAMP is just unable to verify that.
