Push date and time to a string field

[Nic Omaha]

Hello, I am trying to generate a unique ID in a string field on a catalog item. What I would like to populate it with is 

"CONTR" +" current date time" in a string, that way it will always be unique. So for example 

CONTR04132023102731

Any thoughts on how this could be done? Im also open to other ways to set the string field to CONTR + unique number.

Worked in both client and server scripting you can achieve this using:

var unique = "CONTR" + Date.now();

Hi,

You can use the Number maintenance table. The same way it generates Incident / Change number etc., it will be unique and you can give a prefix too. 

Check this: Record numbering (servicenow.com)

If you want to use time as you asked for  you can use this in a server side script

"CONTR"+new GlideDateTime().getNumericValue()

Output
