Since I always seem to return to this page whenever I want to format dates in ruby I'd like to add the following snippet here: Time.now.strftime("%Y-%m-%d %H:%M") => "2010-02-27 15:00"

Check out http://strfti.me for a very readable online reference and sandbox where you can experiment with different strftime format strings.

%e actually gives you the day of the month, with a space instead of a 0. %l give you the hours of the day with a space instead of zero. %g gives you the last two digits of the year 2-digit year (00-99) ...and you know what - just see the C reference for a complete listing: http://linux.die.net/man/3/strftime Also note: In ruby, you can prefix with minus to format out leading zeros, for eg: "%-d/%-m/%y"

And off course with seconds: Time.now.strftime("%Y-%m-%d %H:%M:%S") => "2010-03-12 16:36:33"
