What's New in Edge Rails: 1.month.from_now.no_longer.effed

Brian Donovan has a great writeup of his new Duration fix to the Rails’ Time convenience methods that, until now, have been slightly broken.

Here’s the summary. Before (bad):

Time.now
#=> Thu Jan 25 21:01:31 -0800 2007
1.month.from_now
#=> Sat Feb 24 21:01:34 -0800 2007

Oops – apparently one month only equals 30 days, not really one month. But now, in edge:

Time.now
#=> Thu Jan 25 21:01:31 -0800 2007
1.month.from_now
#=> Sun Feb 25 21:01:34 -0800 2007

And check out this little inspect goodie:

>> 3.weeks
#=> 21 days

And just so you’re not mislead by this post’s title, this fix applies to all the time helpers, not just month.from_now. Read the full rundown to become fully enlightened.

    I hope you copied that wrong, because both of those examples have the wrong day of the week. Feb 24 is a Saturday and Feb 25 is a Sunday. I haven't downloaded and tested yet, but it still looks broken to me.

    Indeed I did copy wrong, Jeremy, tx for the heads up.
