The advanced playback module makes it possible for IRC clients to avoid undesired repetitive buffer playback. IRC clients may request the module to send a partial buffer playback starting from and ending to a certain point of time.
This user module takes no arguments.

The module has been designed to be used together with persistent buffers. Either uncheck Auto Clear Chan Buffer and Auto Clear Query Buffer (Your Settings -> Flags) via webadmin or disable
AutoClearQueryBuffer via controlpanel.
The module implementation is based on the IRC v3.2 message tags  and server time  extensions. The module injects a server time tag (in millisecond precision) to each message sent from ZNC to an IRC client that has requested the
In order for an IRC client to support advanced playback, it should request
znc.in/playback capability and keep track of the latest server time
of received messages. The syntax for a buffer playback request is:
/msg *playback PLAY <buffer(s)> [from] [to]
Where the first argument is a comma-separated list of channels (supports wildcards), and optional last two arguments are number of seconds (floating point for millisecond precision) elapsed since January 1, 1970.
When a client connects to ZNC, it may request the module to play all buffers, starting from *0* (first connect) or the the timestamp of the latest received message (consecutive reconnects).
/msg *playback PLAY * 0
It is also possible to selectively clear playback buffers using the following command syntax:
/msg *playback CLEAR <buffer(s)>
If a client wants to list available buffers, it can use the following command syntax:
/msg *playback LIST [buffer(s)]
The module outputs a list of available/matching buffers, one per line, each followed by the first and last timestamp for the respective buffer.
See also query buffers.
The module also allows configuring client specific buffer limits for identified clients, using the following command syntax:
/msg *playback LIMIT <client> [limit]
A limit of less or equal to 0 clears the limit. Notice that the limit cannot exceed the limit set in the ZNC configuration, but can be used to limit the playback for eg. mobile clients.
ZNC supports passing a client identifier in the password:
