	Does anyone have/know of a program to parse the output of the
'last' command and tell me who was logged in at some arbitrary time?
I'd like to be able to type: 

			whenwho 9:56

and get a list of all the people who were logged in during that particular
minute.  My site resets the wtmp file at 4 AM, so we are not dealing with
infinite output from 'last.'  Awk, perl, C or anything that works reasonably
quickly is fine with me.
