## [Java] Class Duration

- groovy.time.Duration

- Duration represents time periods which have values independent of the context. So, whilst we can't say how long a month is without knowing the year and the name of the month, we know how long a day is independent of the date.

  This is not 100% true for days. Days can actually be 23, 24 or 25 hours long (due to daylight saving adjustments.)

  If you ask Duration to convert itself to milliseconds then it will work on the basis of 24 hours in a day. If you add or subtract it from a date it will take daylight saving into account.
