I don't like the idea of having #now disregard fractional seconds.<br>
Effectively that means that a request for the current time gets<br>

I see your point, but I disagree. To me this is a classic question of "what should the default be?". And the default should be what most users of #now expect. From the code that I've looked at, I still haven't found any place that would benefit from fractional seconds. If that is true, then I think the default should be whole seconds, with a protocol allowing to ask for fractional seconds if that case ever comes up. If you know of any examples in the current system that benefit from fractional seconds in #now I'd really love to see them.<br>

BTW, does anyone know what the result of "Date[And]Time now" is in other systems? What do VW, GST, and others return? Whole seconds or fractional?<br></blockquote><div><br></div><div>VisualWorks answers whole seconds (as did Smalltalk-80 v2):</div>
