But is it the time till this task gets executed? Or is it the maximum time allowed for the task to be completed? I have a task that can take some hours to complete and other times it could be completed in a few minutes (synchronizing data). What whould I set it at? nopCommerce shouldn't cancel it after x seconds.
The time you provided is the time interval when this task will executed. Suppose you want to execute 1 task every 1 hour, then set it as (60min * 60 sec) = 3600 This is what interval only.
