AWS certificate timestamp format

I want to check the expiration date of an SSL certificate placed in the Certificate Manager on my AWS account. When retrieving a certificate from AWS using the CLI - like this:

aws acm describe-certificate --certificate-arn *arn*

I get values looking like '1478433600.0' returned in the "NotAfter" property. I cannot recognize the format and I can't find anything in the docs - can anybody shed some light on this one for me?

http://docs.aws.amazon.com/cli/latest/reference/acm/describe-certificate.html

Best regards

  • That format is

    unix epoch time

    https://en.wikipedia.org/wiki/Unix_time

    The timestamp you pasted represents this date and time:

    Sunday, November 6, 2016 12:00:00 PM
