<para>

The returned list of abbreviations includes all historical use of

abbreviations, which can lead to correct, but confusing entries.

There are also conflicts, as <literal>PST</literal> is used both in the US

and in the Philippines.

</para>

<para>

The list that this function returns is therefore not suitable for building

an array with options to present a choice of timezone to users.

</para>

<note>

<para>

The data for this function are precompiled for performance reasons, and are not updated

when using a newer <link xlink:href="&url.pecl.package;timezonedb">timezonedb</link>.
