Icicles can help you _find_ what you might need to customize:
M-x icicle-vardoc RET .* C-q C-g C-j .*time S-SPC .*mode[- ]line
This shows, as completion candidates, all variables, with their doc strings,
for which all of the following are true:
* the variable name matches anything: .*
* the doc string contains "time": .*time
* the doc string also contains either "mode-line" or "mode line":
The order in the doc string of "time" and "mode-line" (or "mode line") does not
matter - all possible orders are considered when you use `S-SPC'.
The incantation C-q C-g C-j just matches the separator used between variable
name and doc string, for each completion candidate. The default separator is
C-g C-j, and C-q is used to quote the C-q character. (In Icicles, C-j is
self-inserting and does not need to be quoted.)
This quickly shows you the following completion candidates (in *Completions*):
*Non-nil means display minutes to appointment and time on the mode line.
This is in addition to any other display of appointment messages.
*String specifying format for displaying the time in the mode line.
See the function `format-time-string' for an explanation of
how to write this string. If this is nil, the defaults
depend on `display-time-day-and-date' and `display-time-24hr-format'.
*List of functions to be called when the time is updated on the mode line.
*Seconds between updates of time in the mode line.
*List of expressions governing display of the time in the mode line.
For most purposes, you can control the time format using `display-time-format'
which is a more standard interface.
This expression is a list of expressions that can involve the keywords
`load', `day', `month', and `year', `12-hours', `24-hours', `minutes',
`seconds', all numbers in string form, and `monthname', `dayname', `am-pm',
and `time-zone' all alphabetic strings, and `mail' a true/nil value.
For example, the form
'((substring year -2) "/" month "/" day
" " 24-hours ":" minutes ":" seconds
(if time-zone " (") time-zone (if time-zone ")")
(if mail " Mail" ""))
would give mode line times like `94/12/30 21:07:48 (UTC)'.
You can further reduce the number of candidates by filtering with one or more
additional patterns (e.g. S-SPC format).
Even more generally, you can look at all functions and all variables whose doc
strings contain the strings "time" and either "mode-line" or "mode line":
M-x icicle-doc RET time S-SPC mode[- ]line
That shows, as completion candidates, the doc strings of all functions and all
variables that contain both "time" and either "mode-line" or "mode line", in
either order. Click `mouse-2' on any candidate to see it (including the
function or variable name) displayed in *Help*. Again, you can use additional
patterns to further reduce the number of hits.
