<a name="2.B"><h3>2.B. ORDER NOTATION</h3></a>
<p>The order notation in this document is as in DATC, with the following additions for multiversal time travel.</p>
<ul>
<li>A season within a particular timeline is designated in the format X:Y, where X is the turn (starting from 0 and advancing with each movement phase) and Y is the timeline number (starting from 0 and advancing with each timeline fork).</li>
<li>Adjudication is implied to be done between successive seasons. For example, if orders are listed for 0:0 and then for 1:0, it is implied that the orders for 0:0 were adjudicated.</li>
<li>Units are designated by unit type, province, and season, e.g. "A Munich 1:0". A destination for a move order or support-to-move order is designated by province and season, e.g. "Munich 1:0".
<ul>
<li>If season of the ordered unit is not specified, the season is the season to which the orders are being given.</li>
<li>If the season of a unit supported to hold is not specified, the season is the same season as the supporting unit.</li>
<li>If the season of the destination of a move order or the season of the destination of a supported move order is not specified, the season is the season of the moving unit.</li>
<li>For example:
<pre>Germany 2:0
A Munich supports A Munich 1:1 - Tyrolia</pre>
The order here is for Army Munich in 2:0. The move being supported is for Army Munich in 1:1 to move to Tyrolia in 1:1.</li>
