Hi,
Anyone can help, on how to get the total number of days with this data;
{:date_created=>"2008-12-19",
:date_last_updated=>"2008-12-23"}
The display in "puts" should be the total difference.
Thanks in Advance!

You can then divide that by 86400 to get the time in days. If you get a float back, and just want whole days, then just call .to_i or ''round'' on it. eg puts "Created about #{((yourhash[:date_last_updated] - yourhash[:date_created])/86400).round } days ago" If you want it in days and hours, that''s a bit more longwinded but you could write a method to do it. It always seemed to me that Ruby is missing a ''duration'' class that represents the difference between two times, with nice methods for displaying the difference in hours, days, months, years etc. Is there one and i missed it? -- Posted via http://www.ruby-forum.com/. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
