Subject: Last Circulation timestamp for reports
X-Git-Url: https://old-git.evergreen-ils.org/?a=commitdiff_plain;h=4a2b6049eadf5e42982189bb0c03f485a6056ac2;p=evergreen%2Fmasslnc.git

Last Circulation timestamp for reports

Specifically intended for Weeding reports.

Easily swapped out (if needed) to include legacy circ data,
when available from a migration.
