libvirt users - May 2020 - What is expiry time represents in this format

I see the output.

root@X10SDV-8C-TLN4F:/mnt/config# cat
/var/lib/libvirt/dnsmasq/mgmt-1br1.status
[
  {
    "ip-address": "192.168.27.8",
    "mac-address": "52:54:00:42:21:14",
    "hostname": "vyatta",
    "expiry-time": 1589500228
  }
]

Can you please explain what does the expiry-time mean ? What are its units ?
Please let me know.

Thanks & Regards

Seconds since UNIX epoch of midnight on 1 January 1970. See, for example,
https://www.epochconverter.com/ to convert to a human readable format.

Cheers,

Peter

I will just add to Peter's reply that this file is considered internal 
implementation and therefore its format can change at any point without 
warning. Is there an app that you are building on the top of it, or are 
you just asking out of curiosity?

This file is used by NSS plugin though. So for instance if you enable 
'libvirt' NSS plugin, you can 'ssh vyatta' or 'ping
vyatta' directly.
