Fields
Remarks
A DurationDurationDuration is a duration of time that is expressed by the Gregorian year, month, day, hour,
minute and second components. Note that the order relation on DurationDurationDuration is a partial order
For example, the order of the durations one month (P1M
) and 30 days (P30D
) cannot be determined.
