What's Your Problem

If I configure a "fetch_time" over 09:59 in configure.yaml it does not work.
Example:
If I configure
fetch_time: 10:00
I will get the following message (in Verify and restart):

Invalid config for 'waste_collection_schedule' at configuration.yaml, line 38: Invalid time specified: 600 for dictionary value 'waste_collection_schedule->fetch_time', got 600
