Its value is

1

Documentation:
Delay before displaying local help.
This is used if `help-at-pt-display-when-idle' is enabled.
The value may be an integer or floating point number.

If a timer is already active, there are two ways to make the new
value take effect immediately. After setting the value, you can
first call `help-at-pt-cancel-timer' and then set a new timer
with `help-at-pt-set-timer'. Alternatively, you can set this
variable through Custom. This will not set a timer if none is
active, but if one is already active, Custom will make it use the
new value.

You can customize this variable.
