What you want is a job/cron job, background process, daemon ..

Any language that can write into your blogs database will do. Even a 
shell script could work. With ruby you can use Ruby DBI or some other 
mapper of your choice to insert into the database.

Then create an entry in your crontab file (crontab -e) and put the time 
for when you want the script to run.

Depending on your blog software you may also consider posting to your 
blog rather than writing to the database. Check mtsend.py as an example 
(there are ruby versions also, cant recall, for writing to wordpress and 
other blogs).
