The only scheme that is part of "standard R" is the "POSIX"
based one which (conceptually) *includes* the "Date" class.
Use the "Date" class [i.e. first use as.Date() ] unless you
need times in addition to dates, where I'd recommend you
consider 'POSIX' ...
BTW: there is no 'Date' package [at least not in an official
place] as you claim below.
