Date based conditional items in templates

[Opserty]

You'd need something like this in a template (e.g. showthread)

<if condition="$thread['dateline'] < (TIMENOW - (28 * 24 * 60 * 60))">
    YOUR MESSAGE HERE
</if>

The bit in red is how long ago the cutoff date is (in seconds). So 60x60x24x28 is approx. a month (or 28 days), I hope. :erm:

You may need to try $threadinfo if $thread does not work.
