In oauth2, is expires_in is in seconds or miliseconds?

Question

I got this sort of thing in oauth2

{
  "token_type": "Bearer",
  "expires_in": 43200,
  "access_token": "eyJ0eXAiOiJKV1QiLCJhbGciOiJSUzI1NiIsImp0aSI6IjExMzk2NGY3MDZiNGM0ZTJhYTFiM2M4NGQ1Y2YwYWRhMjA4OWIwNDc2ZjM3NjlhN2I1ZTBmZDNkN2YyM2IxYmUxNWE0N2Y0YTU4YmYzMzE1In0.eyJhdWQiOiIxNDQiLCJqdGkiOiIxMTM5NjRmNzA2YjRjNGUyYWExYjNjODRkNWNmMGFkYTIwODliMDQ3NmYzNzY5YTdiNWUwZmQzZDdmMjNiMWJlMTVhNDdmNGE1OGJmMzMxNSIsImlhdCI6MTU1NDc4NzQ3MSwibmJmIjoxNTU0Nzg3NDcxLCJleHAiOjE1NTQ4MzA2NzEsInN1YiI6IjMxOTgwMSIsInNjb3BlcyI6WyJ0cmFkZSIsInByb2ZpbGUiXX0.blR3PYblZtYvd0VOnaePaUFu_dkE2yhbGgBLTHqXGuvaMC-57OhXaWNxLLjLzlHrL1bTJcMUYfRrBNhbpiLe9ln7FofuoRUfSm0IhBuvgX-5Le1k0KLd-1JdFW8Y1jIOYm8jGT7WdBRD3ykPoWAKcp_iuXgv2Ci_beii6W6ANX4BWShpekBuUfcKQoiXLNpmDWNt8SfbF4MDjDCs-Z81HAtzFr4P7lmMFugkqODOgVYg9VEhAdXWG56K8uTBmdc0v7w1Ahy7DE_wWzOMOA6JPq6qUvoIuz51I7LCLLhXUNeLXpELuXzREKqSbgZJb2KaZ67vbFYEM4dt8s67SKWfMv5KK7OPY6v0zB529m3r5H0wfvNOH7PNw782q9AmOSZc62yXCKijBNP-7XKsrzbK2LneVn8z_wDLJ3xjs7frppkQ0f-YAk3xmg8JJnPWDleLm4FUx32F2_MwPlN227ThgASi2N8jtRpkUgNFnOkBScDhEwpT5zqJK9H09pTkUIWdDCB7H5er0HR9qBK509qif4b9UGl1OHMnjQKyFQT36c5nGJCG05E0IRH8Mbax37Wv94Eb_53rpJwEWv_XkuT-N_wPEwf92VvwCUhoHxTK9a-p78NfCuroRQWARk4gdhZ9i_rCgQQEzlEk9EsiFl_bTcBgT7bU",

  "expire": 1554787516031
}

I changed the access token and refresh token a bit

Now there is expires_in 43200. Is that second or milisecond or years or what?

I used this code

Public Shared Function currentTimeStamp() As Int64
    Dim utime = (DateTime.UtcNow - unixEpoch()).TotalMilliseconds
    Return CLng(utime)
End Function

    Dim jtoken1 = JToken.Parse(jtoken2)
    Dim accesstoken = jtoken1.Item("access_token")
    Dim expirytime = jtoken1.Item("expires_in")
    Dim currentTimeStamp = jsonHelper.currentTimeStamp()
    Dim timeexpire = currentTimeStamp + CLng(expirytime)
    Dim refreshtoken = jtoken1.Item("refresh_token").ToString
    jtoken1.Item("expire") = timeexpire

That seems to be a bit wrong.

Is there any documentation that can clearly says it's seconds or milliseconds?

Answer 1

expires_in is value in seconds
