Allow time filters on date fields in CiviReport

This code allows reports to take time filters - ie.

register_date_from = 2011-01-01
register_date_from_time = 6PM

It should work with URL filters.

I have been adding the fields to my report through a hacky method of over-riding the addDateRange function on the report instance

function addDateRange( $name, $label = 'From:', $dateFormat = 'searchDate', $required = false )

{ $this->addDateTime( $name . '_from', $label , $required, array( 'formatType' => $dateFormat ) ); $this->addDateTime( $name . '_to' , ts('To:'), $required, array( 'formatType' => $dateFormat ) ); }

It seems that it would make sense to add to CRM_Core_Form a function

function addDateTimeRange( $name, $label = 'From:', $dateFormat = 'searchDate', $required = false ) {
$this->addDateTime( $name . '_from', $label , $required, array( 'formatType' => $dateFormat ) );
$this->addDateTime( $name . '_to' , ts('To:'), $required, array( 'formatType' => $dateFormat ) );

However, to use it on the report it then requires an additional constant (I think) , altering $this->addFilters & altering CRM_Core_Form_Date::buildDateRange(

It wouldn't be TOOO bad but I have too many questions to tackle it

However, this minor patch does seem to give a small bit of useful extra functionality
