Documentation:
This is a property list, with the following keys:

:max-duration Mark clocking chunks that are longer than this time.
This is a time string like "HH:MM", or the number
of minutes as an integer.

:min-duration Mark clocking chunks that are shorter that this.
This is a time string like "HH:MM", or the number
of minutes as an integer.

:max-gap Mark gaps between clocking chunks that are longer than
this duration. A number of minutes, or a string
like "HH:MM".

:gap-ok-around List of times during the day which are usually not working
times. When a gap is detected, but the gap contains any
of these times, the gap is *not* reported. For example,
if this is ("4:00" "13:00") then gaps that contain
4:00 in the morning (i.e. the night) and 13:00
(i.e. a typical lunch time) do not cause a warning.
You should have at least one time during the night in this
list, or otherwise the first task each morning will trigger
a warning because it follows a long gap.

Furthermore, the following properties can be used to define faces for
issue display.

:default-face the default face, if the specific face is undefined
:overlap-face face for overlapping clocks
:gap-face face for gaps between clocks
:no-end-time-face face for incomplete clocks
:long-face face for clock intervals that are too long
:short-face face for clock intervals that are too short

You can customize this variable.

This variable was introduced, or its default value was changed, in version 24.1 of Emacs.
