handle wrong formatted date argument

Browse Source 
The provided date argument (--date, --datebefore or --dateafter) is parsed by
datetimp.strptime(). This function throws as ValueError exception at failure.

This patch implements exception handling by catching the ValueError exception,
printing an error message and exiting with a non-zero exit code.
