+8.1.1 Time Synchronization</a></h3><P CLASS="para">Time synchronization can be very important to programmers. Consider the following options:</p><PRE CLASS="programlisting">
+time service = yes
+dos filetimes = yes
+fake directory create times = yes
+dos filetime resolution = yes
+delete readonly = yes</pre><P CLASS="para">
+If you set these options, Samba shares will provide the kind of compatible file times that Visual C++, <EM CLASS="emphasis">
+nmake</em>, and other Microsoft programming tools require. Otherwise, PC <EM CLASS="emphasis">
+make</em> programs will tend to think that all the files in a directory need to be recompiled every time. Obviously, this is not the behavior you want.</p><DIV CLASS="sect3">
+<H4 CLASS="sect3">
+<A CLASS="title" NAME="ch08-pgfId-958495">
+8.1.1.1 time server</a></h4><P CLASS="para">
+If your Samba server has an accurate clock, or if it's a client of one of the Unix network time servers, you can instruct it to advertise itself as an SMB time server by setting the <CODE CLASS="literal">
+time</code> <CODE CLASS="literal">
+server</code> option as follows:</p><PRE CLASS="programlisting">
+[global]
+	time service = yes</pre><P CLASS="para">
+The client will still have to request the correct time with the following DOS command, substituting the Samba server name in at the appropriate point:</p><PRE CLASS="programlisting">
+C:\NET TIME \\<CODE CLASS="replaceable"><I>server</i></code> /YES /SET</pre><P CLASS="para">
+This command can be placed in a Windows logon script (see <a href="ch06_01.html"><b>Chapter 6, <CITE CLASS="chapter">Users, Security, and Domains </cite></b></a>).</p><P CLASS="para">
+By default, the <CODE CLASS="literal">
+time</code> <CODE CLASS="literal">
+server</code> option is normally set to <CODE CLASS="literal">
+no</code>. If you turn this service on, you can use the command above to keep the client clocks from drifting. Time synchronization is important to clients using programs such as <EM CLASS="emphasis">
+make</em>, which compile based on the last time the file was changed. Incorrectly synchronized times can cause such programs to either remake all files in a directory, which wastes time, or not recompile a source file that was just modified because of a slight clock drift.</p></div><DIV CLASS="sect3">
+<H4 CLASS="sect3">
+<A CLASS="title" NAME="ch08-pgfId-958501">
+8.1.1.2 time offset</a></h4><P CLASS="para">
+To deal with clients that don't process daylight savings time properly, Samba provides the <CODE CLASS="literal">
+time</code> <CODE CLASS="literal">
+offset</code> option. If set, it adds the specified number of minutes to the current time. This is handy if you're in Newfoundland and Windows doesn't know about the 30-minute time difference there:</p><PRE CLASS="programlisting">
+[global]
+	time offset = 30</pre></div><DIV CLASS="sect3">
+<H4 CLASS="sect3">
+<A CLASS="title" NAME="ch08-pgfId-958505">
+8.1.1.3 dos filetimes</a></h4><P CLASS="para">
+Traditionally, only the root user and the owner of a file can change its last-modified date on a Unix system. The share-level <CODE CLASS="literal">
+dos</code> <CODE CLASS="literal">
+filetimes</code> option allows the Samba server to mimic the characteristics of a DOS/Windows machine: any user can change the last modified date on a file in that share if he or she has write permission to it. In order to do this, Samba uses its root privileges to modify the timestamp on the file. </p><P CLASS="para">
+By default, this option is disabled. Setting this option to <CODE CLASS="literal">
+yes</code> is often necessary to allow PC <EM CLASS="emphasis">
+make</em> programs to work properly. Without it, they cannot change the last-modified date themselves. This often results in the program thinking <EM CLASS="emphasis">
+all</em> files need recompiling when they really don't. </p></div><DIV CLASS="sect3">
+<H4 CLASS="sect3">
+<A CLASS="title" NAME="ch08-pgfId-958509">
+8.1.1.4 dos filetime resolution</a></h4><P CLASS="para">
+<CODE CLASS="literal">
+dos</code> <CODE CLASS="literal">
+filetime</code> <CODE CLASS="literal">
+resolution</code> is share-level option. If set to <CODE CLASS="literal">
+yes</code>, Samba will arrange to have the file times rounded to the closest two-second boundary. This option exists primarily to satisfy a quirk in Windows that prevents Visual C++ from correctly recognizing that a file has not changed. You can enable it as follows:</p><PRE CLASS="programlisting">
+[data]
+	dos filetime resolution = yes</pre><P CLASS="para">
+We recommend using this option only if you are using Microsoft Visual C++ on a Samba share that supports opportunistic locking.</p></div><DIV CLASS="sect3">
+<H4 CLASS="sect3">
+<A CLASS="title" NAME="ch08-pgfId-958515">
+8.1.1.5 fake directory create times</a></h4><P CLASS="para">
+The <CODE CLASS="literal">
+fake</code> <CODE CLASS="literal">
+directory</code> <CODE CLASS="literal">
+create</code> <CODE CLASS="literal">
+times</code> option exists to keep PC <EM CLASS="emphasis">
+make</em> programs sane. VFAT and NTFS filesystems record the creation date of a specific directory while Unix does not. Without this option, Samba takes the earliest recorded date it has for the directory (often the last-modified date of a file) and returns it to the client. If this is not sufficient, set the following option under a share definition:</p><PRE CLASS="programlisting">
+[data]
+	fake directory create times = yes</pre><P CLASS="para">
+If set, Samba will adjust the directory create time it reports to the hardcoded value January 1st, 1980. This is primarily used to convince the Visual C++ <EM CLASS="emphasis">
+nmake</em> program that any object files in its build directories are indeed younger than the creation date of the directory itself and need to be recompiled.</p></div></div></div></div></blockquote>
