display field info in only one line rather than 2 line ?

I have the same behavior in a view showing events since updating to 7.x-2.9. The date and time is displayed on one line if no end date is shown, but two lines if the end date (in this case, end time) is shown.

Here's what the HTML looks like:

<div class="field field-name-field-date field-type-datetime field-label-hidden view-mode-full">
<div class="field-items">
<div class="field-item even">
<span class="date-display-single">
Saturday, October 17, 2015 -
<div class="date-display-range">
<span class="date-display-start" content="2015-10-17T13:00:00-05:00" datatype="xsd:dateTime" property="dc:date">1:00pm</span>
to
<span class="date-display-end" content="2015-10-17T15:00:00-05:00" datatype="xsd:dateTime" property="dc:date">3:00pm</span>
</div>
</span>
</div>
</div>
</div>

I did a little workaround in the view:

1. Change the date display to show only Start Date.
2. Hide that field.
3. Add another date field showing only End Date.
4. Rewrite the results of the second date field as [field_date] to [field_date_1]

Not ideal, but I have no idea how to fix it for real.

I had the same problem today and fixed it with css:

.node-event .date-display-range { display: inline; }

The ".node-event" was added to restrict this to a single content type. It's optional.

Please see #2570239: Display date range as span instead of div for a patch.
