Hard to say "why" but you should note that "h:m" is NOT a permutation of {h,m s} so this behavior really is not contravening the documentation. I check to see of out.format might be different since the format spec is really for input rather than output and it does not accept a two parameter version either: Error in chron(dates = dts, times = tms, out.format = (times = "h:m")) : misspecified chron format(s) length > > same outcome. > > Does updating to R 3.0.0 solve the problem?
