 * It seems that something is wrong in the Queue timings and Crons.
 * I see different current server time and different time shown in GD Queue.
 * See a capture at the very same time of WP time and GD Queue time.

 * I mean the next GD queue run time is behind the current time ….. whatever that
   means for the execution ….

 * Hi,
 * WordPress cron is really a pseudo cron, it doesn’t really run at the exact time
   it should, something has to trigger it (loading of any page does it), so actual
   execution of the cron can be delayed until the trigger happens. If you need cron
   to be run on the exact time, you should set up server-based cron that will trigger
   WordPress cron. I do that for all my websites.
 * The cron from my plugin has it run after you visited the page? If it has, that
   proves the cron delay until the trigger. If it hasn’t, then, you have some other
   cron related issue on your website.

 * I don’t use internal CRON but a 5 minutes Cpanel CRON.
 * I will have to test more this, since it seems that i also get double or triple
   emails (same email).
 * Thank you

 * When plugin processes queue, it reads the emails and immediately marks them as
   in processing to avoid duplicate sending. If you get duplicated emails, something
   is wrong with your cron, and it is possible that cron is fired more than once
   at the same time so that two processes manage to get the data before the emails
   are marked as in processing.
 * WordPress cron has protection for this case that works really well, and I never
   had an issue with it. You should monitor how often the cron is firing and is 
   their instances of firing multiple times at the same time.

 * Well i route to your plugin all emails from stock WP (no dups), i route emails
   from wpForo forum plugin (no dups). But all dups seems to come from a specific
   plugin.
 * I will have to closely look at this, most probably nothing to do with your plugin,
   since disabling GD Queue doesn’t seem to solve the problem.
 * Many thanks for the explanations.

 * I’m posting more information, just in case someone searches in the future about
   STUCK Crons in WordPress.
 * It appears that maybe ALL WordPress plugins that disable WP Updates somehow make
   CRONS stuck for a while.
 * At least all 4 i tried showed the very same problem. So if you use any WordPress
   plugin to Disable Updates, check your CRONS if stuck (and you do not know it,
   as i did). With CRONTROL plugin. If you see some job stuck showing (NOW) for 
   more that a few seconds, then you know you have a problem.
