Hi arichexe,<br />
<br />
time() would give you current time in seconds since epoch ...<br />
Subtract 7 * 24 * 3600 from this value ... this would give you time 7 days ago ... <br />
To get other representations of this time, use ctime/ctime_r etc<br />
<br />
time_t val = time (NULL);<br />
val = val - (7 * 24 * 3600);<br />
printf (&quot;%s&quot;,ctime(&amp;val));<br />
<br />
Cheers!<br />

C is a general-purpose, imperative computer programming language, supporting structured programming, lexical variable scope and recursion, while a static type system prevents many unintended operations. By design, C provides constructs that map efficiently to typical machine instructions, so it has found lasting use in applications that had formerly been coded in assembly language, including operating systems as well as various application software for computers ranging from supercomputers to embedded systems. It is distinct from C++ (which has its roots in C) and C#, and many later languages have borrowed directly or indirectly from C.
