I think last no longer uses wtmp. But the past two days, I have gotten this:

Code: 
last

wtmp begins Fri Oct 21 09:43
I need last sometimes to figure out the hours that I worked. Anyone know how to get more history?
 
This happened again... Now, last works. So it must have to "figure it out" somehow.

Grrr!!!. My cron jobs are not working.

(This is with Lion.)
 
Update: if you become root via sudo, then do last, it will pause a few seconds and then spew out the answers. I believe after that point it will also work for non-root users.
 
Open /Applications/Utilities/Console app and look at logs to see if you see it there. Then if you want to rerun your log cleaning jobs then down an application like Yasu or Onyx and run all the "cleaning routines and let the program reboot your Mac. Then after that boot immediately reboot again to completely rebuild your system's startup/shutdown cache.

The unix way of running those "cron" jobs is running the Terminal command:
Code: 
sudo periodic daily weekly monthly
Plus you learn all about this by the web site Running the Mac OS X maintenance scripts.
