In the days of dialup internet, I used a phone company that offered, between 1900 and 0700, free calls for calls under 30m. So I wrote a cron job that, at 1905, started a script which sat in a loop, dropping the connection, dialing again, and then `sleep` for 29m, until the time got to 0655. Very stupid, but it worked, I guess.
