Description of Problem:

I suggested this on the mailing list:
I'm not sure what the best UI would be but... 

Suppose I get an email with the folowing text:
``The meeting will be at 3 next Monday''
I would like to be able to select this text and have a context-menu entry 
of ``add to calendar.'' This would first popup a dialog to create a new 
calendar entry could be used, with the date of Monday, October 1, 2001 and 
a time of 3PM. The text of the event could be the entire string or just 
``the meeting will be at'' or something even more clever.


BACKEND:
The core of this would be a function that took a string as input and 
returned a date, time, and comment. It would need to do a fair ammount of 
smart pattern matching. Some cases to look for would be:
  ``next [day of week]''
  ``09/30/2001'' or ``9/30/01'' or ``9/30'' or ``the 30th'' or ``sunday''
  ``noon'' or ``12'' or ``12pm''

A simple and useful start would be a function that simply matched for (in 
perl):

if ($input =~ /(\d{1,2})\/(\d{1,2})(\/\d{2,4}){0,1}/ ) { #get 1/1 or 1/1/02
  $month = $1;
  $day_of_month = $2;
  $year = &get_four_digit_year($3);
} elsif ($input =~ /($monthregexp)\W{1,3}(\d{1,2})/i ) { #get english date
  $month = &get_numeric_month($1);
  $day_of_month = $2;
  if ($month >= $this_month) {
    $year = $this_year;
  } else {
    $year = $this_year+1; 
  } 
}
#Next quickly do time range:
$timeregexp = "\\d+\\s{0,1}(am|pm|a|p)";
if ($input =~ /($timeregexp)((\s+\-\s+|\s+to+\s+)($timeregexp)){0,1}/i ) {
   $startime = &time_from_string($1);
   if ($4) {
      $endtime = $4;
   }
}


UI:
  *If ``events'' could be identified accurately, a button or hyperlink 
could be displayed in the message. This would be cool if and only if it 
worked very well.
  *Instead of popping up an add event dialog, a wizard might be better to 
force the user to serialize his/her checking that the date and time is 
correct.
