dndn of the entry to refresh.
ttlTime in seconds (between 1 and 31557600) that the client requests that the entry exists in the directory before being automatically removed.
From RFC:
The responseTtl field is the time in seconds which the server chooses
to have as the time-to-live field for that entry. It must not be any
smaller than that which the client requested, and it may be larger.
However, to allow servers to maintain a relatively accurate
directory, and to prevent clients from abusing the dynamic
extensions, servers are permitted to shorten a client-requested
time-to-live value, down to a minimum of 86400 seconds (one day).
FALSE will be returned on error.
