I'm sometimes having some debates with guys around a given question in stackoverflow, and I realise the answer I upvoted previously is not the one I should have. The problem is that I sometimes realise it 7-10 minutes afterwards, and then it's not possible to cancel the 1st upvote.

what is the underlying intention in this? Couldn't be the delay 10 minutes?

    Vote after realized! Or wait for edit. :) – hims056 Mar 8 '13 at 12:18

    The 2nd upvote is not the problem, I also want to cancel the 1st upvote – Sebas Mar 8 '13 at 12:20
  • Second upvote? AFAIK we can cast only one vote per post. Either upvote or downvote. – hims056 Mar 8 '13 at 12:22

    there are 2 upvotes for 2 answers. I want to cancel the 1st one but it is too late (10 minutes) – Sebas Mar 8 '13 at 12:25

    The best solution here is to exercise more discretion before you vote. Sometimes it happens you misvote anyway, of course; but just be more careful. – Andrew Barber Mar 8 '13 at 12:46
  • the delay is really short. 5 minutes, a coworker comes to ask you a question and that's it. – Sebas Mar 8 '13 at 13:34

The timeout limit for changing votes is a known feature and designed feature, and as for the reason for it Jeff addressed that in comments on his answer here.

Now there isn't a problem for voting more than one answer that you think is good. The "best" answer is accepted, and there can only be one; however you can up vote all the answers you think are good so don't feel the need to retract just because a "better" answer came in.

If you choose to upvote a question and later regret your decision because you realize it's wrong in some way, then leave a comment. The author may address your concern in a way you didn't consider before or may make an edit. Once a post is edited, then you can change your vote.

Finally in regards to the exact time for the timeout, you know... it was changed to 10 minutes, according to Murphy's law from then on out, it would only be the 11th minute you realized you didn't want to do that up vote. ;)

  • No, that's definitely different 5 minutes than 10 mimutes. In my case there are not 2 good answers, really only one should have been upvoted – Sebas Mar 8 '13 at 13:33
  • Also worth noting, the grace period for changing a vote is the same grace period for editing before a new revision is recorded. If one changes, the other really should follow, and it would be very problematic if the editing grace period was any longer than it is. – Tim Post Mar 8 '13 at 13:35
  • @Sebas - no problem, then my 3rd paragraph applies. Comment and ask for the owner of that answer to change what is wrong to make it a good answer worthy of an up vote. – Mike Mar 8 '13 at 13:36
