I’ve also tried using ‘orderby’ => ‘meta_value’ and a combination of meta_query arrays where ‘key’ => ‘start_time’ and I still haven’t gotten the posts to sort correctly.
In fact, where it seemed at first to be doing doing a numerical sort and ignoring the UNIX timestamp format, I’m querying three other post types that use identical custom fields and it looks like there’s really no sorting going on at all, with events coming in any order (3, 2, 5 and 6pm, for example, in one of the post archives).
Thanks!
