How to Add a Date and Time Stamp to a Signature in Acrobat Reader for Android
Question details
The user wants to know how to automatically include a date and time stamp when placing a signature on a PDF document using a mobile app.
- Product
- Acrobat Reader for Android
- Device & OS
- Android
- Scenario
- Signing a PDF document on an Android device where verifying the exact time of the signature is necessary for record-keeping.
- Observed behavior
- The signature is successfully added to the PDF, but no date or time information is displayed alongside it, and there is no visible setting to enable automatic timestamps.
Ensure your Acrobat Reader app is updated to the latest version from the Google Play Store to access all available Fill & Sign tools for manual entry.
Use the Text Tool to Manually Add a Date and Time
Since automatic timestamps are not supported in the Android app, you must manually type the date and time next to your signature.
Adding an automatic date and time stamp to a signature is currently unavailable in the Acrobat Reader mobile application for Android. Automatic timestamps are typically tied to digital certificate signatures available on the desktop version of Adobe Acrobat.
As a practical workaround, you can use the standard text insertion tool to manually type the date immediately after placing your signature.
Open your PDF document in Acrobat Reader for Android, tap the 'Fill & Sign' icon, and tap on the document to place your saved signature.
Tap on the screen away from the signature, or select the 'Add Text' (T) icon from the top toolbar menu.
Tap directly below or next to your signature and manually type the current date and time.
Adjust the text size using the pop-up text menu to match the signature's proportion, then tap the checkmark to save the changes to your PDF.
Submit a Feature Request to the Developers
Request this missing feature directly from Adobe so it can be considered for future Android app updates.

Frequently Asked Questions
Why doesn't my signature automatically show the date in Acrobat Reader mobile?
The Android version of Acrobat Reader currently only supports basic drawn or image-based signatures. These do not include the advanced metadata or automatic timestamping features found in digital certificate signatures on desktop platforms.
Can I use digital certificates to sign PDFs on my Android phone?
Native support for advanced digital certificate signatures (which securely capture automatic cryptographic timestamps) is generally not supported in standard mobile PDF readers. You typically need to use the desktop version of Acrobat or specialized enterprise signing apps.
Is there any mobile app that automatically adds timestamps to signatures?
While standard PDF editors require manual text entry for dates on mobile, specialized electronic signature platforms like Adobe Acrobat Sign or DocuSign automatically capture audit trails and append official timestamps to documents signed on a mobile device.
