issuer information
issuer_url = https://cloudmex.io/

issuer_name = Universidad Tecnologia de Cloudmex
issuer_id = https://raw.githubusercontent.com/chidoman321/profile/master/issuer.json
revocation_list=https://6073a6b0e4e0160017ddfc72.mockapi.io/revocation
issuer_signature_lines={“fields”: [{“job_title”: “University Issuer”,“signature_image”: “images/issuer-signature.png”,“name”: “Your signature”}]}
issuer_public_key=ecdsa-koblitz-pubkey:0x85fca60bBCb1ab6103AD89d176e407aFdCDEe914
my cert-issuer conf_ethtest.ini
issuing_address =0x85fca60bBCb1ab6103AD89d176e407aFdCDEe914
my issuer profile
“publicKey”: [

“id”: “ecdsa-koblitz-pubkey:0x85fca60bBCb1ab6103AD89d176e407aFdCDEe914”,

}
],
example transaction
Ropsten Transaction Hash (Txhash) Details | Etherscan
it only happens on mobile(wallet) , with the universal verifier it doesnt appear
can someone who already did this could help me please ?
Did you try the universal verifier on the same phone?
The error is thrown from this file: cert-verifier-js/ensureValidIssuingKey.js at fe86fc4ed497133e54d7d454ec8dc7fcf8c35e3b · blockchain-certificates/cert-verifier-js · GitHub, if that helps.
So it could be that: txTime = dateToUnixTimestamp(txTime); is returning something inconsistent, or something else. You can look at the conditions and hopefully debug the issue.
yes i tried the universal verifier and the issue doesnt show ,
the problem is at the blockcert wallet ,
aslo with cert-verifier-js ,it returns me the same error

i’m checking ensureValidIssuingKey file
this is before calling ensureValidIssuekey 
For all intent and purposes, the latest version of cert-verifier-js gives a more explicit error message to help figure out the issue.
However in your case, it seems to be beyond that error message. I don’t know why you would have a “invalid date” here and probably need to investigate on your side.
okay broh, i hope my team give me sometime to checkout the issue, also i didn’t tell you, but i am able to bypass the time check if i dont add the key created at profile.json , example 
, also how do you get the time from the eth_ropsten blockchain ?
The time should be retrieved by the explorer, so if you are having problems around that piece, you could inspect what is being returned by the explorer API.
