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