input_datetime always triggers at the earliest setup time

[crazyfacka]

The problem

I use an input_datetime helper with only has_time: true to trigger an automation. The automation is successfully triggered, but always to the earliest time that the input_datetime was set.

Try (1):

1. Set input_datetime to 8:00
2. Automation triggers at 8:00

Try (2):

1. Set input_datetime to 7:30
2. Automation triggers at 7:30

Try (3):

1. Set input_datetime to 8:00
2. Automation triggers at 7:30

The value for the input_datetime is set in the UI using an Entity Card. Looking into the Developer Tools, the timestamp is updated accordingly.
