Hello list,<br><br>Apologies for the cross-post, this originally went to the boost-users list a day or so ago but it got no responses, and then I also realized it was actually more appropriate here.  <br><br>Suppose I have a cross-platform agent that communicates with a server. 
Agent from platform X sends a message to the server which contains a
date/time.  Server sends a message to another agent running platform Y
with the same date/time.  In practice X/Y are always either
windows/linux or linux/windows.  The server always tells the agent
which platform&#39;s native format the time is represented in, so there
should be no problem.  Ideally I&#39;d like to write the following code:<br>
<br>    ptime time;<br>    if (msg.is_from_windows()) <br>    {<br>        time = from_ftime&lt;ptime&gt;(msg.time());<br>    }<br>    else <br>    {<br>        time = from_time_t(msg.time());<br>    }<br><br>But
this doesn&#39;t work because from_ftime&lt;&gt; is not defined on linux. 
If from_ftime&lt;&gt; is already templated on the FILETIME type, is
there any reason it needs to be #ifdef&#39;d out on non-windows platforms?   
I mean, a FILETIME is really just a uint64, can&#39;t the templated function also just operate on a boost::uint64_t?<br>
