Examples

   dt1 = MzQCDateTime$new("1900-01-01")  ## yields "1900-01-01T00:00:00Z"
   dt2 = MzQCDateTime$new(Sys.time())
   ## test faulty input
   ## errors with 'character string is not in a standard unambiguous format'
   try(MzQCDateTime$new('lala'), silent=TRUE)
   ## test roundtrip conversion from/to JSON
   dt2$fromData(jsonlite::fromJSON(jsonlite::toJSON(dt1)))
