Upvoting - Time Returns. Developers?

Attentively watching for minutes the first post.

When refresh the page minutes go back. Because of this, I did not have time to press the button Upvoting before the whale votes for a post. This happens very often when you refresh the page. So I voted for several times, but it was too late and the whale already voted. If you do not keep track of time continuously, it creates the appearance that the time has not yet come and vote early. Or vice versa, you can vote earlier than it should. site will show, for example, that for 27 minutes, but actually only 26.

This phenomenon is extremely negative for all users. So they do not vote in time and accordingly receive less profit. This is a programming error, or what?

What developers say about this?
It can be fixed?
