This is a rather basic option at the moment which only affects the
balance report. I use it as follows, for entering contractor hours into
a project planning application, where $1 is the contractor's timelog
file, and $2 is the date after which new entries appear in the file:
ledger -f $1 balance \
--account=payee \
--time-report \
-d "latest > [$2]" \
--datetime-format='%m/%d/%y %I:%M %p'
