I have a webpage form that requires a date and time to be submitted. When it's submitted I need the back-end to run a script at the time and date specified. Have you ever needed to do something like this?

Some recommendations already posted include:

• The UNIX "at" command
• Setting up a queue system to manage the processes (using something similar to Gearman
• Setting up a cron job to handle the periodic execution of the script.
