Stamp Date and Time

[Dakota_reality6959]

My custom stamp isnt showing up with the current date and time when stamping a document. Im not sure if its the saved location where my stamp is saved or the JavaScript im using.

Hi @Dakota_reality6959,

Thanks for reaching out, and I understand how frustrating it can be when expected stamp behavior stops working.

From your description, it sounds like you’re using a dynamic stamp (like a date/time stamp), but it’s no longer displaying the correct date/time when applied. This usually points to one of the following issues:

Here is what I think:

1. JavaScript Disabled in Acrobat

Dynamic stamps rely on JavaScript to insert live data like the current date/time.

• Go to Acrobat > Preferences > JavaScript

• Make sure “Enable Acrobat JavaScript” is checked

2. Broken or Corrupted Stamp File

The JavaScript logic inside the stamp PDF may be broken or overwritten.

• Navigate to:

  • Windows: C:\Users\<username>\AppData\Roaming\Adobe\Acrobat\<version>\Stamps

  • Mac: ~/Library/Application Support/Adobe/Acrobat/<version>/Stamps

• Try removing the affected stamp file (*.pdf) and re-adding a fresh copy.

• You can also create a new dynamic stamp using Adobe’s Sample Dynamic Stamps from this official resource

3. Testing the Stamp

To confirm if the stamp has

• Select the stamp.

• Use Ctrl + J (Windows) or Cmd + J (Mac) to open the JavaScript Console

• If the console is blank or shows an error, the stamp script may be missing.

 Optional Workaround

If your stamp no longer auto-generates date/time, you can recreate it:

1. Create a new PDF file with a form field that inserts:

var f = this.getField("Today");

f.value = util.printd("mm/dd/yyyy hh:MM tt", new Date());

2. Save this as a custom stamp via:

   • Tools > Stamp > Custom Stamps > Create

Let us know:

• What stamp name are you using (default vs custom)

• If this worked previously and only recently stopped

• Your Acrobat version (Help > About Adobe Acrobat)

• Whether JavaScript is enabled

We’re happy to help troubleshoot further!

What is the script your are using?

[Dakota_reality6959]

var f = this.getField("Today");

f.value = util.printd("mm/dd/yyyy hh:MM tt", new Date()); 

Mainly this one but ive tried different iterations aswell

That should work if the script is a calculation script in a field other than Today.  If it is in the Today field it should read:

event.value = util.printd("mm/dd/yyyy hh:MM tt", new Date()); 

[Dakota_reality6959]

Im not sure what it is. I think im going to just do a type in method rather than auto generated date and time. Thank you to both for helping.

Can you upload the file?

That isn't a stamp file.  It's missing the page template and a propper title.

Just a note. DO NOT EVER USE THE CREATE STAMP TOOLS BUILT INTO ACROBAT. THIS FEATURE DESTROYS DYAMIC STAMPS. 

I hope that's clear.
