# First function will try to filter for EC2 instances that contain a tag named `Scheduled` which is set to `True`
# If that condition is meet function will compare current time (H:M) to a value of the additional tags which defines the trigger `ScheduleStop` or `ScheduleStart`.
# Value of the `ScheduleStop` or `ScheduleStart` must be in the following format `H:M` - example `09:00`
#
# In order to trigger this function make sure to setup CloudWatch event which will be executed every minute.
# Following Lambda Function needs a role with permission to start and stop EC2 instances and writhe to CloudWatch logs.
