What's the correct syntax for OData v4 duration in URI?

I'm trying to get new products in last day. Having this URI query:
http://ift.tt/1OkwU9V ge (now() sub P1D0H0M0.0S)
But it returns message: The query specified in the URI is not valid. Syntax error at position 37 in 'CreatedOnUtc ge (now() sub P1D0H0M0.0S)'.
What am I having wrong here?
