As of v184.108.40.206, time triggers can not be edited to change the time, or even check on the scheduled times. The only indicator you have is what you labeled the trigger with at the time of creation.
If possible, please allow time triggers to be edited. This will make it easier to reschedule things without the need to recreate triggers, and then re-add all the actions for a trigger.
As Triggers only add to the bottom of the list, it makes seeing the organization difficult. Please allow for manual re-ordering of the triggers, or at least Alphabetical/numerical organization based on the user-defined name of the trigger.
I see there are some similar suggestions.
