<h2>Slstatus date with alternative locale</h2>
<h3>2025-04-26</h3>
<h4>Modifying slstatus to display French date</h4>
<p>My default locale is en-US, but I wanted to display weekdays in French in the slstatus bar.</p>
<p>The solution is to add setlocale to the function in <br><b>slstatus/components/datetime.c</b></p>

#include &lt;stdio.h&gt;
#include &lt;time.h&gt;
<b>#include &lt;locale.h&gt;</b>

#include "../slstatus.h"
#include "../util.h"


const char *
datetime(const char *fmt)
{    
	<b>setlocale(LC_ALL,"fr_FR.utf8");</b>
	time_t t;

	t = time(NULL);

	if (!strftime(buf, sizeof(buf), fmt, localtime(&t))) {
		warn("strftime: Result string exceeds buffer size");
		return NULL;
	}

	return buf;
}
