   ### Over-permissive truthy value check <sub>![category

   ###### What is the issue?
   The fallback for non-array values using double negation could interpret 
non-empty strings or numbers as valid time comparisons
   
   ###### Why this matters
   Using !! operator will convert any truthy value (like strings or numbers) to 
true, which could incorrectly indicate that time comparison is enabled when it 
shouldn't be.
   
   ###### Suggested change ∙ *Feature Preview*
   Restrict the accepted values to only valid time comparison inputs:
   ```typescript
   const timeComparisonStatus = Array.isArray(timeComparevalue) ? 
timeComparevalue.length > 0 : false;
   ```
