[pmwiki-users] Time-based conditional markup

[Randy]

Can anyone suggest a technique to include some lines from a page only  
if that page was modified within the past two hours?

I've installed MarkupExprPlus and ConditionalExtensions, but still  
find the problem difficult since it requires using the results of a  
calculation in a conditional. (I'm not keen on allowing users to  
manipulate arbitrary variables via $EnableExprVarManip - that seems  
like it would present security problems.)
