It just so happens that I have a script that runs every Monday morning that checks for expired, locked, and about-to-expire accounts. It generates a report and emails the report to specific users. Since this does 173% of what you need, I've posted it here and you can remove the unwanted parts and customize it to your specific needs..

The core pieces are there - look for accounts that are locked, send email. \:\)

;;AUTHOR         Glenn Barnas 
;; 
;;VERSION        2.2 / 2007/10/14 
;;		 Modified to increase accuracy, permit fracional second calculations 
;;		 2.1 / 2007/03/17 
;;               added "now" and "today" options for both start and end times 
;;               2.0 / 2006/11/20 
;;               Changes for code efficiency; added defaults for midnight  
;; 
;;ACTION         Calculates the time difference between two given date/time strings 
;; 
;;SYNTAX         TimeDiff(Start [, End] [, Format] [, MSec]) 
;; 
;;PARAMETERS     Start  - REQUIRED, String value representing the start timestamp 
;;                 Format yyyy/mm/dd hh:mm:ss 
;; 
;;               End    - OPTIONAL, Defaults to "now" 
;;		   String value representing the ending time 
;;                 Format yyyy/mm/dd hh:mm:ss 
;;		   Can be the special value "now" for the current date/time, or "today" 
;;                 for midnight of the current day. 
;; 
;;                 When the time value is not specified, it defaults to 00:00:00.000 (midnight) 
;; 
;;		 Format - OPTIONAL, one of: 
;;		  "m" - return minutes 
;;		  "h" - return hours 
;;		  "d" - return days 
;;		  "y" - return years 
;;		 When a format value is specified, it returns the fractional part (ie 0.5 days for 12 hours). 
;; 
;;		 MSec	- OPTIONAL, True if the fractional seconds should be returned. Default 
;;		  is false, returning whole seconds, to maintain compatibility with earlier versions. 
;;		  MSec only affects the return of fractional seconds, not fractional parts of other time formats. 
;; 
;;REMARKS        Returns a value representing the difference in time between two date/time 
;;		 strings. Assumes that "Start" is in the past, but will properly return a 
;;		 negative value if it is in the future. 
;; 
;;RETURNS        Double - difference between Start and End timestamps in seconds
