Certificate for time stamping

Help
#1

Sorry in advance for being off topic.

Does anyone know a publicly trusted CA, when signing a CSR with

extendedKeyUsage = critical,timeStamping

keeps this extended key usage in the certificate?

Let's Encrypt does not offer the timeStamping EKU.

I'm not sure who will issue one. A good way to investigate is looking at who has signed other certificates with time stamping:

Searching on Censys for parsed.extensions.extended_key_usage.time_stamping:true and parsed.extensions.basic_constraints.is_ca:false should show that
