array_intersect() [function.array-intersect]: Argument #1 is not an array in /www/drupal/modules/date/date.inc on line 1680.

Oop, you're right. I knew I'd forget something :-) I'll get it into the next commit.

Hmm, no it should be OK. I have been having some problems getting my files to update correctly (I do a cvs update but sometimes I still have the previous version) so maybe something like this has happened. Anyway, I have also committed some other changes so try picking up all the very latest commits. I am pretty sure there is no problem if you have all the latest files, but reopen if you do.

I just uploaded the latest version of date-4.7.0 (last revised 10/1/06) and am having the same problem. It happens whenever I try to save a CCK content type configuration regardless of whether the content type has a date field in it or not.

 *  a function to figure out if any time data is to be collected or displayed
 */
function date_has_time($granularity) {
  return sizeof(array_intersect($granularity, array('H', 'N', 'S'))) > 0 ? TRUE : FALSE;
}

Don't know if this is relevant but I do have some date fields in CCK content types that do not contain time values (only date information).

This issue was originally reported for cvs and cvs is fixed. If you're having a problem in 4.7 that is a different issue, so I'll change the version. I'll take a look at that later today.

Now fixed in both versions.

Fixes it for me in 4.7 - Thanks Karen
