Time.new does not work as I would expect - ruby-on-rails

Question

I am trying to generate some seed material.
seed_array.each do |seed|
Task.create(date: Date.new(2012,06,seed[1]), start_t: Time.new(2012,6,2,seed[2],seed[3]), end_t: Time.new(2012,6,2,seed[2] + 2,seed[3]), title: "#{seed[0]}")
end
Ultimately I will put random hours, minutes, seconds. The problem that I am facing is that instead of creating a time with the 2012-06-02 date it creates a time with a different date: 2000-01-01.
I tested Time.new(2012,6,2,2,20,45) in rails console and it works as expected. When I am trying to seed my database however some voodoo magic happens and I don't get the date I want.
Any inputs are appreciated. Thank you!
Update1:
(0.0ms) begin transaction SQL
(0.5ms) INSERT INTO "tasks" ("created_at", "date", "description",
"end_t", "group_id", "start_t", "title", "updated_at") VALUES (?, ?,
?, ?, ?, ?, ?, ?) [["created_at", Tue, 03 Jul 2012 02:15:34 UTC
+00:00], ["date", Thu, 07 Jun 2012], ["description", nil],
["end_t", 2012-06-02 10:02:00 -0400], ["group_id", nil],
["start_t", 2012-06-02 08:02:00 -0400], ["title", "99"],
["updated_at", Tue, 03 Jul 2012 02:15:34 UTC +00:00]]
(2.3ms) commit transaction
This is a small sample of the log.
Update 2
Task id: 101, date: "2012-06-26", start_t: "2000-01-01 08:45:00", end_t: "2000-01-01 10:45:00", title: "1", description: nil, group_id: nil, created_at: "2012-07-03 02:15:33", updated_at: "2012-07-03 02:15:33"
This is what shows up in rails console.

Answer 1

Sounds like you used the :time type for your start_t and end_t. In that context time refers to a pure time of day data type, with no date, because that's what the SQL time type is.
Ruby's Time type covers both date and time, so your database column needs to be :datetime. In fact ruby has no pure time of day class so activerecord uses a regular Time with a bogus date instead.

Answer 2

I have tested you code like this:
arr = [1,2,3]
arr.each do |seed|
Timetest.create(time: Time.new(2012,6,2,2,20,45), title: "#{seed}")
end
And its working as expected. But i got this sql on my console and its a bit different than yours in your start_t and end_t
SQL (4.1ms) INSERT INTO "timetests" ("created_at", "time", "title", "updated_at") VALUES (?, ?, ?, ?) [["created_at", Tue, 03 Jul 2012 02:11:35 UTC +00:00], ["time", Sat, 02 Jun 2012 07:20:45 UTC +00:00], ["title", "1"], ["updated_at", Tue, 03 Jul 2012 02:11:35 UTC +00:00]]
Update 1
Have you tried to use DateTime.new instead of Time.new?
Task.create(date: DateTime.new(2012,06,seed[1]), start_t: DateTime.new(2012,6,2,seed[2],seed[3]), end_t: DateTime.new(2012,6,2,seed[2] + 2,seed[3]), title: "#{seed[0]}")
