Plugins » Katello

Foreman 1.16 introduced two helpers that should be used whenever date/time information is printed.

date_time_absolute(time, format = :short)
date_time_relative(time)

If it's applicable, the Foreman dependency of a plugin should be bumped to 1.16. In Katello specifically it might be more complicated as the bastion can't use helpers directly. I see two ways, either doing the same in bastion or having server generating this date in right format and bastion just wrapping it with the right tags.
