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.DurationOps._

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.

  6. def +(delta: Duration): 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.

    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.
