I have created a scheduled rule that sends a email based on a date field in nodes of a certain content type. The rule executes as scheduled and the email is sent but for some reason it only fires exactly a hour after its supposed to.
E.g on the admin/config/workflow/rules/schedule page the item is scheduled to execute at Thu, 2017-08-03 15:30 but I only receive the email at 16:30.
I could fix this by adding a offset to the trigger time but I would rather want to understand why this is happening and fix the problem accordingly.
