Duration 

Companion object Duration

sealed class Duration extends TimeLike[Duration] with Serializable

A `Duration` represents the span between two points in time. It represents this with a signed long, and thus the largest representable duration is:

106751.days+23.hours+47.minutes+16.seconds +854.milliseconds+775.microseconds+807.nanoseconds

Durations may be constructed via its companion object, `Duration.fromNanoseconds`, `Duration.fromSeconds`, etc. or by using the time conversions:

```import com.twitter.conversions.time._

3.days+4.nanoseconds```

In addition to the timespans in the range of `Long.MinValue` to `Long.MaxValue` nanoseconds, durations have two distinguished values: `Duration.Top` and `Duration.Bottom`. These have special semantics: `Top` is greater than every other duration, save for itself; `Bottom` is smaller than any duration except for itself — they act like positive and negative infinity, and their arithmetic follows. This is useful for representing durations that are truly infinite; for example the absence of a timeout.

3. def %(x: Duration)

Scales this `Duration` by modding by `x`.

4. def *(x: Double)

Scales this `Duration` by multiplying by `x`.

5. def *(x: Long)

Scales this `Duration` by multiplying by `x`.

6. def +(delta: Duration)

Adds `delta` to this `TimeLike`.

Adds `delta` to this `TimeLike`. Adding `Duration.Top` results in the `TimeLike`'s `Top`, adding `Duration.Bottom` results in the `TimeLike`'s `Bottom`.

19. def ceil(increment: Duration)

Rounds up to the nearest multiple of the given duration.

Rounds up to the nearest multiple of the given duration. For example: 127.seconds.ceiling(1.minute) => 3.minutes. Taking the ceiling of a Time object with duration greater than 1.hour can have unexpected results because of timezones.
