CMS Made Simple Forums

Occasionally I need to add temporary content alerting visitors to something that will cease to be relevant on a certain date. For this I create a Global Content Block and manually add and remove it from the relevant page.

Is there an easy way to schedule a GCB to be removed on a given day e.g. not displayed beyond a certain unix time? A plugin with parameters for the GCB and unix time of start and end times maybe?

something like this should work:

That's certainly simple and effective! Thanks very much.
