<li class="listitem">
The base of the specified version number. "<code class="computeroutput"><span class="identifier">BOOST_PREDEF_MAKE_0X</span></code>"

<p>
Date decomposition macros return a date in the relative to the 1970 Epoch
date. If the month is not available, January 1st is used as the month and
day. If the day is not available, but the month is, the 1st of the month
is used as the day.
