(timeclock-relative, timeclock-ask-before-exiting)
(timeclock-use-display-time): Doc changes.
(timeclock-modeline-display): Give a message if
`timeclock-use-display-time' is non-nil but `display-time-mode' is not
active.
(timeclock-time-to-date, timeclock-workday-remaining)
(timeclock-time-to-seconds, timeclock-seconds-to-time): Move earlier
in the file so defined before used.
(timeclock-status-string): No need for `let*' so use `let'.
(timeclock-query-out): Always return a non-nil value.
(timeclock-ask-before-exiting): Put `timeclock-query-out' on
`kill-emacs-query-functions' rather than `kill-emacs-hook'.
(timeclock-mode-string): Doc fix.
(timeclock-modeline-display): Doc fix. Use `global-mode-string' rather
than `mode-line-format'.
(timeclock-query-out): Doc fix.
(timeclock-update-modeline): No need for `let*', so use `let'.
Add some help-echo text to `timeclock-mode-string'.
(timeclock-mode-string): Give it the risky-local-variable property,
so that help-echo text will display.
(timeclock-find-discrep): Set `accum' to 0 if `timeclock-discrepancy' is nil.
time is remaining.
(timeclock-workday-elapsed): Don't accept a "relative" argument for
the current day's elapsed time. What could that have meant?
(timeclock-workday-elapsed-string): No "relative" argument anymore.
(timeclock-when-to-leave): Changed logic, similarly to what was done
for `timeclock-workday-remaining'.
(timeclock-find-discrep): Removed "today-only" argument, which had no
meaning. Fixed some more math problems. The function now returns a
three member list: (TOTAL-TIME-DISCREPANCY TODAYS-TIME-DISCREPANCY
TODAYS-ELAPSED-TIME).
