in reply to Best and Worst Nodes of The last month / year
But they are not of the last 30 days nor 365 days! They are of the last 30*24*60*60 seconds and 365*24*60*60 seconds (roughly)!
So you've only somewhat reduced the inaccuracy. And you don't care about weeks?? Everyone should have a user setting that says whether their week starts on Sunday or Monday and we'll recompute the superlative nodes lists separately for each person.
And timezones mean that we need to compute the other lists separately for each user as well.
Or, we could just realize that from Jan 18th 2004 through Jan 17th 2005 is a duration of one year and so listing the best nodes of the year "as of X date" and not "the best nodes of 2005 so far", is just fine.
