'f.time_field with 24 hour clock - Rails Fields

I've got a little Rails app that I need to use the 24-hour clock for inputting times. Right now, I've got:

  <div class=".col-md-7">
    <%= f.label :backinservice %><br>
    <%= f.time_field :backinservice %>
  </div>

Which gives an AM/PM option. When I input a time like 18:56, it automagically converts it to 06:56 PM. Normally that would be totally ok, just not in this app.

I also tried:

  <div class=".col-md-7">
    <%= f.label :recieved %><br>
    <%= f.time_field :recieved, :format=>"%H:%M" %>
  </div>

But that doesn't work either.

Is there a :format option that allows for straight use of the 24-hour clock?

Solution 1:[1]

I had to do the following to get this to work for me:

<%=
    f.time_field :my_time_field,
    value: f.object.my_time_field.strftime("%H:%M")
  %>

Found this out by looking at the definition of time_field, that is only creating a new instance of Tags::TimeField.new

In turn Tags::TimeField.new only does one thing which is to define the format.
