find . -name "*a.log" -exec perl -pi -e 's|Work done at (dd/mm/yy hh:mm):|Work done at:|g' {} \;

Looks a bit cryptic, but searches for all *a.log files, and starts perl to replace
all occurences of "Work done at (dd/mm/yy hh:mm)" with "Word done at:". Better try
this first with a copy of your logbook. After you successfully changed that, you
have to modify the attribute list in elogd.cfg accordingly, like

Attirbutes = ..., Work done at, ...

Please note that after each manual modification of the logbook files, you have to
restart elogd.
