'man bash' shows:

+++
TMOUT
If set to a value greater than zero, TMOUT is treated as the default timeout for the read builtin. The select command terminates if input does not arrive after TMOUT seconds when input is coming from a terminal. In an interactive shell, the value is interpreted as the number of seconds to wait for input after issuing the primary prompt. Bash terminates after waiting for that number of seconds if input does not arrive.
+++

Simply put, if the number is bigger than 0, and you leave the shell at a prompt for longer than that value, it closes the shell (logs out).

This appears to have the exact same functionality as the same variable in KSH.

From either $HOME/.bash_profile or /etc/bashrc for all:

export TMOUT=0
export TMOUT=3600 (* 1 hour *)
export TMOUT=1800 (* 30 minutes *)
export TMOUT=60 (* 1 minute *)
etc.
