try_verify_against_date sanity check date command

Browse Source 
Sanity check `date` command used in tests `try_verify_against_date_command`
and `try_verify_against_date_command_format`. Make sure it's the kind of
`data` command expected (accepts `--version`).
Also, it's just good to print this for debugging purposes.
