<dfn>Clocks</dfn> in Ardour are used to display <dfn>time values</dfn> precisely.
In many cases, they are also one way to edit (change) time values, and in a few
cases, the only way. All clocks share the same basic appearance and functionality,
which is described below, but a few clocks serve particularly important roles.
<dfn>Clocks</dfn> in Ardour are used to display time values
precisely. In many cases, they are also one way to edit (change) time
values.
</p>
<p>
In the transport bar of the editor window there are two clocks (on a large enough
screen), that display the current position of the playhead
and additional information related to transport control and the timeline. These
are called the <dfn>transport clocks</dfn>; the left one is the primary
transport clock and the right one is the secondary transport clock.
In the transport bar of the editor window there are two clocks by
default, that display the current position of the playhead and
additional information related to transport control and the timeline.
These are called the <dfn>transport clocks</dfn>; the left one is the
<dfn>primary transport clock</dfn> (always showing the playhead
position) and the right one is the <dfn>secondary transport
clock</dfn>.
</p>
<p>
All the clocks in Ardour share the same powerful way of editing time. Refer to
<a href="@@editing-clocks">Editing Clocks</a> to learn how.
Having two transport clocks allows seeing the playhead position in
two different time units without having to change any settings. For
example, one can see the playhead position in both timecode units and
BBT time. The secondary transport clock can nevertheless be hidden in
the <a
href="@@preferences#preferences-appearance-toolbar">Preferences</a>,
at <kbd class="menu">Appearance &gt; Toolbar &gt; Display Secondary
Clock</kbd>.
</p>
<p>
Editing the time in the transport clocks will reposition the playhead in the same
way that various other editing operations will.
</p>
<h2>The Special Role of the Secondary Transport Clock</h2>
<p>
On a few occasions Ardour needs to display time values to the user, but there
is no obvious way to specify what units to use. The most common case is the big
cursor that appears when dragging regions. For this and other similar cases,
Ardour will display time using the same units as the secondary clock.
</p>
<h2>Why are there two transport clocks?</h2>
<p>
Having two transport clocks allows seeing the playhead position in two different
time units without having to change any settings. For example, one can see the
playhead position in both timecode units and BBT time.
</p>
<h2>Special Modes for the Transport Clocks</h2>
<p>
In addition to the time-unit modes, each of the two transport
clocks (again, on a sufficiently large screen) can be
independently set to display <dfn>Delta to Edit Point</dfn> in whatever time
units its current mode indicates. This setting means that the clock shows the
distance between the playhead and the current edit point, and it may show a
positive or negative value depending on the temporal order of these two points.
The clocks will use a different color when in this mode to avoid confusion.

Refer to <a href="@@editing-clocks">Editing Clocks</a> to learn how.
Editing the time in the transport clocks will reposition the playhead
in the same way that various other editing operations will.
</p>
<p>
To switch either (or both!) of the transport clocks into this mode, use
<kbd class="menu"> Edit &gt; Preferences &gt; Transport</kbd> and select
the relevant checkboxes.
The transport clocks have special attributes due to their function:
</p>
<h2>Information panel</h2>
<p>
Note that when in <samp>Delta to Edit Point</samp> mode, the transport clocks
cannot be edited.
Under each clock is an information panel, that offers informations about the current <a href="@@editing-clocks#clock-modes">clock mode</a>:

<table class="dl">
<thead>
<tr>

<th>Timecode / Minutes:Second / Seconds</th>

<h2>The Big Clock</h2>
<h2>Time origin</h2>
<p>
To show the current playhead position in a big, resizable window, activate
<kbd class="menu">Window &gt; Big Clock</kbd>. The big clock is very useful
when working away from the screen but still wanting to see the playhead
position clearly (such as when working with a remote control device across
a room). The big clock will change its visual appearance to indicate when active
recording is taking place. Below on the left is a screenshot showing a fairly
large big clock window filling a good part of the display, and on the right,
the same clock during active recording.
In the <kbd class="mouse">Right</kbd>-click menu, it is possible to
change the time origin, i.e. the zero-point in time, amongst :

<ul>
<li>
The transport clock may display a positive or negative value
depending on the temporal order of the chosen zero value and the
playhead.
</li>
<li>
The clocks will use a different color when in <em>delta to
edit</em> or <em>delta to origin</em> mode to avoid confusion.
</li>
<li>
Also, when in the two later modes, the value of the clock can not
be edited.
