Invalid JWT when trying to connect to Google Oauth for google API
<p>I was trying to connect to Google API through OAuth through JWT, but I keep getting this error:</p>

<blockquote>
  <p>{ "error": "invalid_grant", "error_description": "Invalid JWT: Token must be a short-lived token and in a reasonable timeframe" } </p>
</blockquote>

<p>In my JWT calim I set the iat to be current time minus 1970-01-01 in seconds and exp to iat + 3600, so I do not know why I am still getting this error. If anyone knows the answer please tell meeeeee!</p>
