From the original question:

There will be a special interface for the director of the project in which he will decide at what time he wants the email sent to him

This says to me that the code running the director's interface needs to schedule the reporting program (which sends the email) to be run at a time specified by the director, i.e. configure a cron job to run it at the required time. And presumably the director is free to change this, so a one-time setup of cron will not work.

kidd, try reading the man page for the at command. This would be an easier way to do scheduling - just use backticks to call at. You could set the reporting program to reschedule itself each time it is run.

An alternative approach would be for the director's interface to accept a time and store this in a file or database somewhere. Have your reporting program check this file on startup and only send the email if the current time = the requested time. Then use cron to run this script at frequent intervals, say every 5 minutes.

• Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:

  <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>

• Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
