Carpet: add current walltime to timing group
Issue #2267
closed
Pull request is here https://bitbucket.org/eschnett/carpet/pull-requests/26/carpet-add-current-walltime-to-timing/diff
This helps correlating events on a cluster for which a timestamp is available with actions (and iteration numbers) in Cactus similar to adding a timestamp to `CCTK_VInfo` output (which Cactus can already do).
Unless objected I will apply this after 2019-07-13.
