I want to check if an hour has passed since the current time. When I  
run  
return (DateTime.now \> (@session[‘user’].account\_info.last\_reward +  
0.04))

it returns the correct value I think, but when I put that same thing  
(without the return) in an if statement, it tells me it can’t compare  
a datetime and a time. Not sure how to compare them then…

You have to convert one to the other’s same class.

What does this say?

(@session[‘user’].account\_info.last\_reward + 0.04).class
