Concise Binary Object Representation (CBOR) is a binary data serialization format loosely based on JSON authored by Carsten Bormann and Paul Hoffman. [ a ] Like JSON it allows the transmission of data objects that contain name–value pairs , but in a more concise manner.
It is similar to the Object class in Java or C# and is satisfied by any type, including built-in types like int. [ 74 ] : 284 Code using the empty interface cannot simply call methods (or built-in operators) on the referred-to object, but it can store the interface {} value, try to convert it to a more useful type via a type assertion or type ...
Screenshot of PTPd 2.3.1, an implementation of PTP for Unix-like systems. Precision Time Protocol (PTP) is a widely adopted protocol for delivery of precise time over a computer network.
It contains the name of a tree object (of the top-level source directory), a timestamp, a log message, and the names of zero or more parent commit objects. [ 63 ] A tag object is a container that contains a reference to another object and can hold added meta-data related to another object.
The current epoch of 1 January 1970 00:00:00 UTC was selected arbitrarily by Unix engineers because it was considered a convenient date to work with. The precision was changed to count in seconds in order to avoid short-term overflow. [1] When POSIX.1 was written, the question arose of how to precisely define time_t in the face of leap seconds ...
Common methods of ETag generation include using a collision-resistant hash function of the resource's content, a hash of the last modification timestamp, or even just a revision number. In order to avoid the use of stale cache data, methods used to generate ETags should guarantee (as much as is practical) that each ETag is unique.
In computing, timestamping refers to the use of an electronic timestamp to provide a temporal order among a set of events. Timestamping techniques are used in a variety of computing fields, from network management and computer security to concurrency control .
The term "timestamp" derives from rubber stamps used in offices to stamp the current date, and sometimes time, in ink on paper documents, to record when the document was received. Common examples of this type of timestamp are a postmark on a letter or the "in" and "out" times on a time card .
