@UnstableApi
class SntpClient

Static utility to retrieve the device time offset using SNTP.

Summary

Nested types
`interface SntpClient.InitializationCallback` Callback for calls to `initialize`.

Constants
`const String!`	`DEFAULT_NTP_HOST = "time.android.com"` The default NTP host address used to retrieve `getElapsedRealtimeOffsetMs`.
`const Int`	`DEFAULT_TIMEOUT_MS = 1000` The default maximum time, in milliseconds, to wait for the SNTP request to complete.

Public functions
`java-static Unit`	`initialize(loader: Loader?, callback: SntpClient.InitializationCallback?)` Starts loading the device time offset.

Public properties
`java-static Long`	`@GuardedBy(value = "valueLock") elapsedRealtimeOffsetMs`
`java-static Boolean`	`@GuardedBy(value = "valueLock") isInitialized`
`java-static Long`	`@GuardedBy(value = "valueLock") maxElapsedTimeUntilUpdateMs`
`java-static String!`	`@GuardedBy(value = "valueLock") ntpHost`
`java-static Int`	`@GuardedBy(value = "valueLock") timeoutMs`

const val DEFAULT_NTP_HOST = "time.android.com": String!

The default NTP host address used to retrieve getElapsedRealtimeOffsetMs.

const val DEFAULT_TIMEOUT_MS = 1000: Int

The default maximum time, in milliseconds, to wait for the SNTP request to complete.

java-static fun initialize(loader: Loader?, callback: SntpClient.InitializationCallback?): Unit

Starts loading the device time offset.

Parameters
`loader: Loader?`	A `Loader` to use for loading the time offset, or null to create a new one.
`callback: SntpClient.InitializationCallback?`	An optional `InitializationCallback` to be notified when the time offset has been initialized or initialization failed.
