in sqlalchemy, can query similar to: self.session.query(jobsrunning).filter((datetime.datetime.utcnow() - jr.start_time) > datetime.timedelta(hours=3)).all() this fails because i'm assuming datetime.datetime.utcnow() returns double after being subtracted jr.start_time . there way around without pulling datetime.datetime.utcnow() outside of query itself? for some, may make query cleaner.
