dateFormat property
The date format that you are using. Valid values are auto
(case-sensitive), your date format string enclosed in quotes, or NULL. If
this parameter is left unset (NULL), it defaults to a format of
'YYYY-MM-DD'. Using auto recognizes most strings, even some
that aren't supported when you use a date format string.
If your date and time values use formats different from each other, set this
to auto.
Implementation
