[BUG] timefmt

Describe the bug

It is impossible to use a blank datefmt ("").

import logging
from logging import debug, error, info
from rich.logging import RichHandler

logging.basicConfig(format="%(message)s",
                    handlers=[RichHandler(rich_tracebacks=True)],
                    datefmt="",
                    )

error(f"something or other")

The above forces a date:

[12/07/23 09:35:40] ERROR    something or other                                                                     test.py:10

Changing the datefmt to be a single space instead works, but adds a space to the front of the line:

                    datefmt=" ",

  ERROR    something or other                                                                                       test.py:10

Platform

Platform: linux (but shouldn't matter)

platform="Linux"
enrich==1.2.7
rich==12.5.1

(I tried to create a patch, but failed -- not familiar enough with the internal flow handling of the date formatting)

Hello @hardaker. I have found a few solutions to this issue

1. using a lambda

logging.basicConfig(format="%(message)s",
                    handlers=[RichHandler(rich_tracebacks=True)],
                    datefmt=lambda x: "", # since we can provide a Callable
                    )

2. Using a escape char

logging.basicConfig(format="%(message)s",
                    handlers=[RichHandler(rich_tracebacks=True)],
                    datefmt="\0",
                    )

3. Using the RichHandlers log_time_format property

logging.basicConfig(format="%(message)s",
                    handlers=[RichHandler(rich_tracebacks=True, log_time_format='')],
                    )
