You could try setting up a test where you schedule two jobs to clash to say, increment an integer column in a test table and see what happends. if they clash then you can design the job steps to conditional execute based on querying sysjobs (for job_id GUID based on job name) and sysjobschedules for date/time values, both tables are in msdb. The advanced tab can be set for the job step to conditional execute. Hope this helps.
