You now of bobobase_modification_time?
But you can replace it anyway, I just copied and pasted from existing code:


<dtml-in "ZopeFind(this(), obj_expr='bobobase_modification_time() >= 
ZopeTime()-1')">


combine that with the various dtml-in variables (sequence-start/end/)
and dtml-else and you'll indeed can shrink your code somewhat.
