Comment (by wildworks):

 @codekraft Thank you for explaining it in detail.

 > Here is how it happens using public functions:
 > 1. If a third-party plugin accidentally passes a float between 0 and 1
 (e.g., `0.5`, maybe due a wrong calculation), the validation `!
 is_numeric( 0.5 ) || 0.5 <= 0` evaluates to `false`. The error check is
 bypassed.
 > 2. The event is passed to the core system to be saved.
 > 3. When WordPress sets this in the multidimensional cron array, PHP
 automatically truncates the `0.5` float key into an integer `0`.

 I think this is certainly a problem that needs to be solved.
