elapsed_watch

https://github.com/tamouse/elapsed_watch

Reading a file of events, containing an event name (a string) and a date-time string (yyyy-mm-dd hh:mm(:ss)), print a nice duration since the event (if the event occurs in the past) or until the event (if the event occurs in the future). The impetous for this little program is my wanting to know how long it has been since my last cigarette.
