message to meet, such as before a given time or after a given time. Then choose the time. The filter compares 
the message's time stamp to the system clock when the filter is run, or to a specific time and date you 
choose from a calendar. You can also have it look for a message within a range of time relative to the 
filter, such as two to four days ago.</p></item>
