     HeirsLockTimeEdit - A custom QWidget for editing locktime values in the context of heirs distribution.
-    
+
     This widget combines raw locktime editing with date-based selection and provides
     additional functionality for managing locktime values in a heir inheritance scenario.
-    
+
     Features:
     - Supports both raw locktime values and human-readable date formats
-    - Emits valueEdited signal when the locktime value changes
+    - Emits valueEdited signal when the locktime value is edited
     - Provides threshold-based validation for locktime values
     - Integrates with heir distribution workflows
-    
+
+    Behavior:
+    The class handles three types of locktime values:
+    1. **Timestamps**: Raw integer values representing Unix timestamps
+    2. **Day intervals**: Values ending with 'd' (e.g., '3d' = 3 days from now)
+    3. **Year intervals**: Values ending with 'y' (e.g., '2y' = 2 years from now)
+
+    Only these formats are valid:
+    - Examples: '1609459200', '3d', '2y'
+    - Invalid: 'invalid', '5m', '10x'
+
+    The widget automatically converts day/year intervals to appropriate timestamps.
+
     Attributes:
         valueEdited (pyqtSignal): Signal emitted when the locktime value is edited
         locktime_threshold (int): Minimum threshold value for locktime (default: 50000000)
-    
+
     Args:
         parent: Optional parent QWidget
         default_index (int): Default index for the combo box (default: 1)
