no way to set option allowFuture

[mprokopov]

from documentation:

To support timestamps in the future, use the allowFuture setting:
jQuery.timeago.settings.allowFuture = true;

but here is no such option support in gem

You can just set it in your application.js:

//= require rails-timeago
jQuery.timeago.settings.allowFuture = true;

Perhaps helpful for others, I had a problem when implementing the proposed configuration.

Even when configuring the allowFuture option, any future dates/times were not being processed. This was due to the fact that they weren't created with the data-time-ago attribute by the timeago_tag helper (and so weren't matched by the time[data-time-ago] jQuery selector).

In order to resolve the problem, you need to either specify a limit in the future:

<%= timeago_tag 1.day.from_now, limit: 1.year.from_now %>

Or enable the force option:

<%= timeago_tag 1.day.from_now, force: true %>

Either of these options could alternatively be specified in an initialiser.
