Using Cloud KMS and HSM, need Timestamping

[Pratik Dwivedi]

Hi, 

We are using google cloud KMS to successfully sign PDF documents, but need to add timestamping to enable long term validity. 

Does Google also provide a timestamping service ? 

Any recommendations regarding a timestamping service that would allow adding timestamps to a signed PDF file. 

Thanks

Currently Cloud KMS does not support document timestamping, You can make a feature request here: https://issuetracker.google.com
