[General] How could this be done?

[[ExiTuS]]

This requires a change of PHP code in showthread.php:

Time ago I managed to achieve that lastpost date with this simple modification:
Add the following variables to the empty line 71 in showthread.php (v1.8.22/.24):

$ets_thread_firstpost_date = my_date('relative', $post['dateline']); $ets_thread_lastpost_date = my_date('relative', $thread['lastpost']);

(Try to keep the original line structure and do not intentionally break lines - so you don't get in any trouble on future code investigations)

The variable can now be used in "Show Thread Templates / showthread", for example:

{$ets_thread_firstpost_date} / {$lang->lastpost}: {$ets_thread_lastpost_date}

Good luck!
