SQL (32.2ms) INSERT INTO "as" ("a", "created_at", "updated_at") VALUES (?, ?, ?) [["a", Sat, 05 Nov 2011 17:30:00 UTC +00:00], ["created_at", Sat, 12 Nov 2011 02:43:05 UTC +00:00], ["updated_at", Sat, 12 Nov 2011 02:43:05 UTC +00:00]]
=> true
注意:日期被解析为UTC而没有时区偏移

这样的事情会起作用。
datetime = DateTime.new(2011,11,05,17,30);
datetime.to_s(:db)
我不确切地知道你是否认为日期和时间是两个单独的字符串
