I don't think either of those are good human engineering. I would
like the preferred Perl 6 form to simply be:
multi sub localtime(Num $?when = time) returns Time::Local { ... }
The time function always returns the time in floating point. In fact,
all numeric times are Num in Perl 6. Then you don't have to worry
about whether picosecond resolution is good enough. Time and
duration objects can, of course, do whatever they like internally,
and among themselves, but someone who says sleep($PI) should get a
$PI second sleep. Our computers are capable of floating point these
days, and I consider any other numeric time format to be cultural
baggage. I particularly loathe any kind of two integer format.
Sorry about the rant, but you seem to have pushed one of my hot buttons...
