[O] Org assumes scheduled/deadline time from headline

[Manuel Koell]

I'm using the org-journal extension from Bastian Berchtold to write my
daily stuff down. Some of my journal entries (headlines) start with a time
like 12:17 or 20:33. When I make a TODO out of it and set a
schedule/deadline date, orgmode assumes the time for the schedule/deadline
date from the headline. How can I prevent this (wrong) behaviour? I guess
it is a feature rather than a bug...
