Notice here: http://www.digitalmars.com/d/2.0/phobos/std_date.html The first alias is: alias d_time; It doesn't state what d_time is aliased to. The same thing happens with typedef. If this is not a bug, then this is an enhancement request for ddoc.

(In reply to comment #2) > Fixed D2 > > https://github.com/D-Programming-Language/dmd/pull/1209 Also note that only alias is included in D2 changeset, since typedef is deprecated I haven't included a fix for it.
D1 is not supported anymore.
