This is standard for all Unices, not Linux specific.  If anything, Linux
is unusual in that it caters to the other case of keeping the hardware
clock in the local timezone, to ease interoperability with Windows (&
DOS) on dual-boot systems.

A system without a default timezone set is exceedingly rare -- all
installations force you to set one (which can be overriden on a
per-process basis by the environment).
