Hi, Name Here....
The most recent task log entries are:
Sun Apr 03 17:16:02 PDT 2011: Testing my solution for blah blah
Sun Apr 03 17:16:49 PDT 2011: Having some entries so I can demonstrate how this should look...
Sun Apr 03 17:19:26 PDT 2011: Finishing the writeup for blah blah
*** What do you plan to work on during this session? ***
Not a whole lot, to be honest.
Thanks!

After this, file ~/.tasklog should have contents like:

Sun Apr 03 17:16:02 PDT 2011: Finishing the writeup for blah blah
Sun Apr 03 17:18:49 PDT 2011: Testing my solution
Sun Apr 03 17:19:26 PDT 2011: Having some entries so I can demonstrate how this should look...
