'''SOURCE_DATE_EPOCH''' is a technique for dealing with the &amp;quot;timestamp problem&amp;quot; that often complicates attempts to produce byte-for-byte reproducible software builds. It was designed primarily by the maintainers of Debian Linux.&lt;br /&gt;
&lt;br /&gt;
The standard defines a &amp;lt;code&amp;gt;SOURCE_DATE_EPOCH&amp;lt;/code&amp;gt; environment variable, containing a timestamp (in [[Unix time]] form), which tools are expected to use instead of other sources of timestamps.&lt;br /&gt;
