In the Untangle UI (Config > Network > DHCP Server) the following fields are available:
- MAC Address
- Address
- Hostname
- Expiration Time

However when I run the following API command over HTTP:
({
"id":297,
"nonce":ec61pq84h9ov52ev9nurmldr95,
"method":".obj#{{configManagerID}}.getActiveDhcpLeases",
"params":[]
}

it doesn't return the expiration time.

Any way to get this information from the API?
