With bug 13049 the behaviour of the was changed, so the number of hours defined for will be recalculated into days now (minimum 1). It would be nice if it was possible again to give the delay in hours. But we should at least change the help of delete_unverified_opac_registrations.pl to point out that limitation.
To be fair, there is a note: IMPORTANT: You should no longer call this script. Please use cleanup_database.pl with parameter --del-unv-selfreg. Totally missed it, was only looking at the options.
Is this obsolete since Bug 21855 ?
Hi Frido, no this is not fixed. The job is now done by the cleanup script, but it still can't be scheduled for hours again.
It also doesn't run on an out-of-the-box installation... Bug 24968
