@ThreadSafe
public final class ClockSkew
extends Object
```
Utility methods for checking and reacting to the current client-side clock being different from the service-side clock.

Method Summary

All Methods Static Methods Concrete Methods
Modifier and Type	Method	Description
`static Duration`	`getClockSkew(Instant clientTime, Instant serverTime)`	Calculate the time skew between a client and server date.
`static Optional<Instant>`	`getServerTime(SdkHttpResponse serviceResponse)`	Get the server time from the service response, or empty if the time could not be determined.
`static boolean`	`isClockSkewed(Instant clientTime, Instant serverTime)`	Determine whether the request-level client time was sufficiently skewed from the server time as to possibly cause a clock skew error.

- Method Detail
  - isClockSkewed
```
public static boolean isClockSkewed(Instant clientTime,
                                    Instant serverTime)
```
    Determine whether the request-level client time was sufficiently skewed from the server time as to possibly cause a clock skew error.
  - getClockSkew
```
public static Duration getClockSkew(Instant clientTime,
                                    Instant serverTime)
```
    Calculate the time skew between a client and server date. This value has the same semantics of HttpClientDependencies.timeOffset(). Positive values imply the client clock is "fast" and negative values imply the client clock is "slow".
  - getServerTime
```
public static Optional<Instant> getServerTime(SdkHttpResponse serviceResponse)
```
    Get the server time from the service response, or empty if the time could not be determined.
