I just think nobody has explained clearly what happens.
The timezone package (called "tzdata" for my RedHat/Fedora systems) is a
set of data tables that map the $TZ (or fallback system time zone value)
eg "Sydney/AUstralia" for me, into a time offset from GMT.
Step one for any UNIX system is to ensure that the system clock is set
to the correct GMT time. Internally, and on the disc filesystems, that
is what is used.
Step two is to specify what local time zone you wish to work in.
For _display_ purposes i.e. in "ls" listings, in mail headers, in the
output of the "date" command, all these call library routines that
take the $TZ setting and look up the timezone data. That obtains an
offset from GMT to your local time. This arithmetic is then done, and
your correct local time displayed to you.
Also, in this way different users may have different local times displayed
to them. For example, if I sshed into your machine I could set $TZ
to Sydney/Australia and have your file times displayed to me in _my_
local time!
So: you do need the "timezone package". It really is just the tables of
time zone names to "local time" offsets. It includes things like summer
time and the like.
That's all you are missing - this data. Install it and be happy.
