I sometimes clock out, then very quickly realize I need to finish one last thing, and I don't
bother to clock back in because it will only take a minute, but then of course it takes
a lot longer. I have a bash command that runs this:
sqlite3 ~/.timetrap.db "update entries set end = NULL where id = (select max(id) from entries);
but it seems it would be better if there was an equivalent within timetrap.
