## Querying time metadata
To obtain the current time as well as some additional metadata about the time,
use the `Query` function:
use the [`Query`](https://godoc.org/github.com/beevik/ntp#Query) function:
```go
response, err := ntp.Query("0.beevik-ntp.pool.ntp.org")
time := time.Now().Add(response.ClockOffset)
```
Alternatively, use the `QueryWithOptions` function if you want to change the
default behavior used by the `Query` function:
Alternatively, use the [`QueryWithOptions`](https://godoc.org/github.com/beevik/ntp#QueryWithOptions)

function:
```go
options := ntp.QueryOptions{ Timeout: 30*time.Second, TTL: 5 }
response, err := ntp.QueryWithOptions("0.beevik-ntp.pool.ntp.org", options)
time := time.Now().Add(response.ClockOffset)
```
The `Response` structure returned by `Query` includes the following
information:
The [`Response`](https://godoc.org/github.com/beevik/ntp#Response) structure
returned by `Query` includes the following information:
* `Time`: The time the server transmitted its response, according to its own clock.
* `ClockOffset`: The estimated offset of the local system clock relative to the server's clock. For a more accurate time reading, you may add this offset to any subsequent system clock reading.
* `RTT`: An estimate of the round-trip-time delay between the client and the server.

* `KissCode`: A 4-character string describing the reason for a "kiss of death" response (stratum=0).
* `Poll`: The maximum polling interval between successive messages to the server.
The `Response` structure's `Validate` method performs additional sanity checks
to determine whether the response is suitable for time synchronization
purposes.
