Is there an option or a variable in HCI to list current date/time in order to compare that to say an object metadata date/time values ?
In what context? When do you want to compare? When querying? In pipeline processing? Some place else?
During pipeline processing possibly after the "Text/Metadata extraction and Date Conversion" stages.
I don't think it currently exists as a pipeline condition.
Can you describe the usecase?
One use case is copying contents based on relative date.
