I'm not sure which of the modules you use but I assume they all work in a similar way.
When you set a publishing schedule for an item, it creates a new publishing schedule task in the database under /sitecore/system/Tasks/Schedules
node.
Then it's processed by TaskDatabaseAgent
. And it all depends on how frequently that agent is configured to be run.
By default it's 10 minutes.
<agent type="Sitecore.Tasks.TaskDatabaseAgent" method="Run" interval="00:10:00"/>
If the last time when TaskDatabaseAgent
was executed is 6 minutes before your scheduled publishing time, it will be executed 4 minutes after your publishing scheduled time, so your item will be "late" by 4 minutes.
You can change the value of the interval
for "Sitecore.Tasks.TaskDatabaseAgent"
to 10 or 30 seconds to make sure your items are published faster.
