Type:Time

Type:Time is for time durations. For dates, optionally with time, use Type:Date.

Type:Time defines a Type:Number whose standard unit is second, corresponding to the s Time unit in SI.

The format of this datatype in RDF Export is an XSD double. Note the Time datatype denotes a time span; this is different from the XML Schema Datatype time, which is a time-of-day.

Use
You can use a property of this type by entering a number of Type:Number and one of several implemented units of time. (You cannot mix units, e.g. half-life:=2 months & 14 days won't work.)

Instead you need to use: time:=2.5 months

Since there are so many units for time, most properties of type time will specify display units so as not to display, for example, people's ages in weeks.

Units
The list below determines the supported time units. Arbitrary SI-Unit prefixes such as k/m/M are not supported, though you can add, for example, ms as an additional "unit".

"Year" is defined as average Julian year, to make the conversion between years and days accurate for any multiple of 4 years within in the period 1901 - 2099.

Check: time:=365.2425 average Julian years

Should be equal to time:=365.25 average Gregorian years

Note: these timespans are based on civil data, not on astronomical values. For further reference see the Article about Time in the English Wikipedia.
