Try using "/bin/date >> /tmp/date.txt" instead. Tilde-expansion may not
be available, and PATH may not be set correctly.

^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
This last line is the only important part. It says that cron attempted to
execute the command.

^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
This shows that there was some output generated by the command you tried
to execute (most likely on stderr). Since you didn't redirect stderr in
your command, cron attempted to mail it to you, and since you're not
running a mail server, that attempt failed.

Try redirecting stderr from your cron command as well. Most likely cron
couldn't find "date" (incorrect PATH setting), or couldn't access
"~/date.txt" (no tilde expansion).
