Methods such as the following should be defined (abstract ideally) in SS_Database, partly as a contract for subclasses to fill, partly to inform developers of cross-platform methods.

e.g. These functions should exist across all DB platforms (and should be used more!)

datetimeDifferenceClause($date1, $date2)

datetimeIntervalClause($date1, $interval)

This seems to be the case already:

• https://github.com/silverstripe/sapphire/blob/3.1/model/Database.php#L960
