CMIS synchronization is delayed due to DateTime comparisons ignoring time

Because DateTime comparisons ignore the time [1], the CMIS synchronization task will always be at least 12 hours behind the actual repository with the following query (perhaps only for content in UTC+1200 timezone), and in some cases changes will not be detected until 36 hours afterwards (depending on Cron job):

// cmis_sync/cmis_sync.cmis.inc line 83
$sync_full_rule =  $sync_map_type['full_sync_next_cron']?'':sprintf('AND cmis:lastModificationDate > \'%s\'', date_create('12 hour ago')->format('Y-m-d\TH:i:s.000-00:00'));

By changing the > to a >=, the CMIS repository can be kept immediately up-to-date.
