- * @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 date - The date to be changed
- * @param duration - The object with years, months, weeks, days, hours, minutes and seconds to be subtracted
