Adding timestamp to an uploaded document

Question

I am trying to add timestamp to the file name is this possible? Here's what i am using in the interface to ingest the time stamp on the uploaded document but it doesn't seem to be working. 
 a!fileUploadField( label: "Upload the pdf", labelPosition: "ABOVE", target: cons!FolderLocation, filenames: substitute(fv!file.name,".",concat(" ",now(),".")), value: ri!file, saveInto: ri!file, validations: {}

Hi Ankur, 
 
 The file name will be changed on submission of the form. 
 
Here is the sample code, I have used 
 
 a!fileUploadField( 
 label: "File Upload", 
 labelPosition: "ABOVE", 
 target: ri!targetFolder, 
 filenames: fv!file.name & datetext( 
 now(), 
 "yyyyddmm hhmmss" 
 ), 
 value: ri!file, 
 saveInto: ri!file, 
 validations: {} 
 )
