Empty String — returns an empty STRING.
Unix Timestamp — returns the current Unix timestamp as an INT. current is freshly generated on every execution. saved returns the value that was stored in the node before this execution; after execution, the new current value is written into last_value so it can be saved with the workflow.
Random Long INT — returns a large positive random INT in the signed 64-bit range. current is freshly generated on every execution. saved returns the value that was stored in the node before this execution; after execution, the new current value is written into last_value so it can be saved with the workflow.

The last_value widget is stored as text so large integers are preserved exactly in workflow JSON without JavaScript number precision loss. On a newly created node, the initial saved value is 0.
