No need for the =E2=80=98rec=E2=80=99 part.  I propose to output all genera=
tions in the
recutils format when =E2=80=98--list-generations=E2=80=99 is passed.

>   "+1m"    =E2=87=92 #<time time-duration ...>   ; 30 days

The plus sign is confusing (we=E2=80=99re subtracting).  I=E2=80=99d rather=
 use =E2=80=9822d=E2=80=99,
=E2=80=982w=E2=80=99, and =E2=80=981m=E2=80=99.

How can I subtract 22 days from (current-time) using SRFI-19?  There is
a =E2=80=98subtract-duration=E2=80=99 procedure, but I don=E2=80=99t unders=
tand how to create a
=E2=80=98duration=E2=80=99 object.

> These are just suggestions, but that seems to make more sense now.

Indeed.

> Apologies for the confusion!

No worries.  Thanks for the tips.
