So the packages may have been selected due to some weak dependency (i.e.
'recommended' by some other package that got installed, or the packages
themselves 'suggest' being installed together with some other package).

If they were introduced by a weak dependency, there needs to be a
trigger-package (the one 'recommending', or the one being referred to by the
'suggests'). Once the trigger-package is installed nothing will happen. The
next time the trigger-package is updated however, is the time where the weak
dependency might be re-evaluated again.

This is NOT the time the package was installed. It just indicates that the
package was installed by a user-request (not automatically added by the
resolver).

This however contradicts the theory of having been added by the resolver as a
weak dependency.

So '2017-09-11 11:03:10' is the time the packages were '|install|'ed. The
history should also contain a line (somewhere above) telling which '|command|'
was executed. 

Probably the yast online update. If you can attach the yast logs containing
this command (or the zypper log in case it was a zypper command) I'll have a
look at them.
