# Duration constructor

const Duration({int days: 0, int hours: 0, int minutes: 0, int seconds: 0, int milliseconds: 0, int microseconds: 0 })

Creates a new Duration object whose value is the sum of all individual parts.

Individual parts can be larger than the next-bigger unit. For example, `hours` can be greater than 23.

All individual parts are allowed to be negative. All arguments are 0 by default.

## Implementation

    const Duration(
        {int days = 0,
        int hours = 0,
        int minutes = 0,
        int seconds = 0,
        int milliseconds = 0,
        int microseconds = 0})
        : this._microseconds(microsecondsPerDay * days +
              microsecondsPerHour * hours +
              microsecondsPerMinute * minutes +
              microsecondsPerSecond * seconds +
              microsecondsPerMillisecond * milliseconds +
              microseconds);
