|
* Convert a interval object to a duration object.
|
||
|
*
|
||
|
* @typeParam DateType - The `Date` type, the function operates on. Gets inferred from passed arguments. Allows to use extensions like [`UTCDate`](https://github.com/date-fns/utc).

|
*
|
||
|
* @param interval - The interval to convert to duration
|
||
|
*
|
||
|
* @returns The duration object
|
||
|
*
|
||
|
* @example
|
||
|
* // Get the duration between January 15, 1929 and April 4, 1968.
|
||
|
* intervalToDuration({
|
||
|

|
||
|
* end: new Date(1968, 3, 4, 19, 5, 0)
