<h3>Changes from Boost 1.29 to 1.30 (date_time 1.00 to 1.01)</h3>
|
|
<p class="bold">
|
|
Notice: The interface to the <font class="el">partial_date</font>
|
|
class
|
|
<a href="date_algorithms.html">(see date_algorithms)</a>
|
|
was changed. The order of construction parameters was changed
|
|
which will cause some code to fail execution. This change was
|
|
made to facilitate more generic local time adjustment code.
|
|
Thus instead of specifying partial_date pd(Dec,25) the code
|
|
needs to be changed to partial_date pd(25, Dec);
