==============
|
|
|
|
**Updates**
|
|
|
|

|
**Changes**
|
|
|
|
* Added a protocol `Version` field to the `Response` struct.
|
|
|
|
Release v1.3.1
|
|
==============
|
|
|
|
**Changes**
|
|
|
|
* Added AES-256-CMAC support for symmetric authentication.
|
|
* Symmetric auth keys may now be specified as ASCII or HEX using the "ASCII:"
|
|
or "HEX:" prefixes.
|

|
Release v1.3.0
|
|
==============
|
|
|
|
**Changes**
|
|
|
|
* Added the `ReferenceString` function to `Response`. This generates a
|
|
stratum-specific string for the `ReferenceID` value.
|
|
* Optimized the AES CMAC calculation for 64-bit architectures.
|
|
|
|
**Fixes**
|
|
|
|
* Fixed a bug introduced in release v1.2.0 that was causing IPv6 addresses
|
|
to be interpreted incorrectly.
|
|
|
|
Release v1.2.0
|
|
==============
|
|
|
|
**Changes**
|
|
|
|
* Added support for NTP extensions by exposing an extension interface.
|
|
Extensions are able to (1) modify NTP messages before being sent to
|
|
the server, and (2) process NTP messages after they arrive from the
|
|
server. This feature has been added in preparation for NTS support.
|
|
* Added support for RFC 5905 symmetric key authentication.
|
|
* Allowed server address to be specified as a "host:port" pair.
|
|
* Brought package into further compliance with IETF draft on client data
|
|
minimization.
|
|
* Declared error variables as part of the public API.
|
|
* Added a `Dialer` field to `QueryOptions`. This replaces the deprecated
|
|
`Dial` field.
|
|
* Added an `IsKissOfDeath` function to the `Response` type.
|
|
|
|
**Deprecated**
|
|
|
|
* Deprecated the `Port` field in QueryOptions.
|
|
* Deprecated the `Dial` field in QueryOptions.
|
|
|
|
Release v1.1.1
|
|
==============
|
|
|
|
**Fixes**
|
|
|
|
* Fixed a missing indirect go module dependency.
|
|
|
|
Release v1.1.0
|
|
==============
|
|
|
|
**Changes**
|
|
|
|
* Added the `Dial` property to the `QueryOptions` struct. This allows the user
|
|
to override the default UDP dialer when setting up a connection to a remote
|
|
NTP server.
|
|
|
|
Release v1.0.0
|
|
==============
|
|
|
|
This package has been stable for several years with no bug reports in that
|
|
time. It is also pretty much feature complete. I am therefore updating the
|
|
version to 1.0.0.
|
|
|
|
Because this is a major release, all previously deprecated code has been
|
|
removed from the package.
|
|
|
|
**Breaking changes**
|
|
|
|
* Removed the `TimeV` function. Use `Time` or `QueryWithOptions` instead.
|
|
|
|
Release v0.3.2
|
|
==============
|
|
|
|
**Changes**
|
|
|
|
* Rename unit tests to enable easier test filtering.
|
|
|
|
Release v0.3.0
|
|
==============
|
|
|
|
There have been no breaking changes or further deprecations since the
|
|
previous release.
|
|
|
|
**Changes**
|
|
|
|
* Fixed a bug in the calculation of NTP timestamps.
|
|
|
|
Release v0.2.0
|
|
==============
|
|
|
|
There are no breaking changes or further deprecations in this release.
|
|
|
|
**Changes**
|
|
|
|
* Added `KissCode` to the `Response` structure.
|
|
|
|
|
|
Release v0.1.1
|
|
==============
|
|
|
|
**Breaking changes**
|
|
|
|
* Removed the `MaxStratum` constant.
|
|
|
|
**Deprecations**
|
|
|
|
* Officially deprecated the `TimeV` function.
|
|
|
|
**Internal changes**
|
|
|
|
* Removed `minDispersion` from the `RootDistance` calculation, since the value
|
|
was arbitrary.
|
|
* Moved some validation into main code path so that invalid `TransmitTime` and
|
|
`mode` responses trigger an error even when `Response.Validate` is not
|
|
called.
|
|
|
|
|
|
Release v0.1.0
|
|
==============
|
|
|
|
This is the initial release of the `ntp` package. Currently it supports the
|
|
following features:
|
|
* `Time()` to query the current time according to a remote NTP server.
|
|
* `Query()` to query multiple pieces of time-related information from a remote
|
|
NTP server.
|
|
* `QueryWithOptions()`, which is like `Query()` but with the ability to
|
|
override default query options.
|
|
|
|
Time-related information returned by the `Query` functions includes:
|
|
* `Time`: the time the server transmitted its response, according to the
|
|
server's clock.
|
|
* `ClockOffset`: the estimated offset of the client's clock relative to the
|
|
server's clock. You may apply this offset to any local system clock reading
|
|
once the query is complete.
|
|
* `RTT`: an estimate of the round-trip-time delay between the client and the
|
|
server.
|
|
* `Precision`: the precision of the server's clock reading.
|
|
* `Stratum`: the "stratum" level of the server, where 1 indicates a server
|
|
directly connected to a reference clock, and values greater than 1
|
|
indicating the number of hops from the reference clock.
|
|
* `ReferenceID`: A unique identifier for the NTP server that was contacted.
|
|
* `ReferenceTime`: The time at which the server last updated its local clock
|
|
setting.
|
|
* `RootDelay`: The server's round-trip delay to the reference clock.
|
|
* `RootDispersion`: The server's total dispersion to the referenced clock.
|
|
* `RootDistance`: An estimate of the root synchronization distance.
|
|
* `Leap`: The leap second indicator.
|
|
* `MinError`: A lower bound on the clock error between the client and the
|
|
server.
|
|
* `Poll`: the maximum polling interval between successive messages on the
|
|
server.
|
|
|
|
The `Response` structure returned by the `Query` functions also contains a
|
|
`Response.Validate()` function that returns an error if any of the fields
|
|
returned by the server are invalid.
