Since many of us still use RHEL and CentOS 6 and 7 as targets of
backported Fedora tools, why would we want to even use time of day?
RPM is such a critical system for legacy and supported releases I'd be
extremely reluctant to expect them to be compatible with what is
essentially an extraneous feature, namely the support of timestamps in
changelogs where they serve no significant functional use. Why publish
By that logic, no feature introduced in RPM would be used until a
decade after it is introduced. Sorry, I'm not willing to wait that
The granular timestamps are useful for reproducibility stuff, as well
as providing an accurate representation of the temporal history.
As a matter of fact, pretty much all packaging formats *except* RPM
require full timestamps in changelogs. Even SUSE changes files include
full timestamps, they're just lost on conversion to RPM changelog at
build time (though that'll stop being true soon).
That said, if *you* want to use the legacy changelog date stamp style,
you can. I still do for many of my packages that are intended to be
EL7 compatible. But for many of us, EL7 is not our concern, so the new
format is perfectly usable.
