> Apache SIS already support the temporal CRS listed in the "name" column of following table. Those CRS are defined in `CommonCRS.Temporal` enumeration:
> ||Name            ||Identifier            ||
> |Julian           |OGC:JulianDate          |
> |Dublin Julian    |SIS:DublinJulian        |
> |Modified Julian  |SIS:ModifiedJulianDate  |
> |Truncated Julian |OGC:TruncatedJulianDate |
> |Unix/POSIX time  |OGC:UnixTime            |
> |Java time        |SIS:JavaTime            |
> However there is currently no way to instantiate those CRS by a call to `CRS.forCode(String)` or to get their URN by a call to `IdentifiedObjects.lookupURN(…)`. We should add the identifiers listed in the "Identifier" column of above column and make sure that they are recognized by above-cited API.
> Some of those CRS appear in the [OGC Definitions Server|http://www.opengis.net/def/crs/OGC/0]. Those CRS are given the "OGC" namespace. Other CRS are (for now) specific to Apache SIS and given the "SIS" namespace. The latter may be changed to "OGC" in any future version if those CRS become defined by OGC.
