1: Please reply on-list; you asked the list, the discussion should remain there. I have added the list to the CC line. 2: Please don't top-post. Quote only the relevant bits of the previous message and reply below. If the message is long, do that in pieces. [quote] reply [quote] reply. Like a conversation. Now, to your questions. A UNIX user would use "cron" to schedule the midnight job and from the midnight job then probably use "at" to schedule the other jobs to run at specific times. See "man 1 crontab", "man 5 crontab" to submit the cron jobs and "man at" to submit the once off jobs. UNIX means Linux, Solaris, AIX, any of the BSDs (includes MacOSX), etc. You could a small python script for the midnight job, and it would submit the "at" jobs. See the "random" module to compute a pseudorandom number (and thus a random time), the "datetime" module to compute the dates and times from that number, and the "subprocess" module to submit the "at" job for the chosen run times. The modules are here: http://docs.python.org/3/py-modindex.html That presumes python 3; if you're using python 2 the docs for that are available at the same web site. You don't need to use "at". Your midnight job could just compute the time in seconds to each job time, then use the "time.sleep" function to delay until then. See the "time" module at the above link. Nobody on this list will write your program for you. Attempt to write the program, then come to the list with your attempt and any problems. People will help if you've made an initial effort, and continue to try. This question has the "feel" of a homework question; the point of homework is for you to learn by solving a problem yourself. It is fine to seek help, but you must make the effort yourself. Come back with specific questions.
