I just double-checked on the server and both the "date" command in terminal as well as the Server Time setting in WHM are showing my server being on CST time:
Current Time
Tue Nov 11 06:13:08 CST 2025Yet in the UBB admin panel I'm seeing the following:
Default Time Offset (Hours):
Unadjusted Server Time: 11/11/2025 12:13Which just so happens to be UTC (or possibly London time during the 6 months when DST isn't in effect).
I checked the file you mentioned and I see something about "servertime" and "RELATIVE_TIME" but still have no idea how the UBB admin panel is showing the unadjusted server time... as different than the actual server time.

Could this be a cache thing or an altered setting elsewhere?
$servertime = $html -> convert_time(time(),"","",1);
...
$relative = "";
if ($config['RELATIVE_TIME']) {
$relative = "checked='checked'";
} // end if
