copied!<p>The definitions in the <code>Etc</code> directory are meant to be POSIX style, thus they have their sign reversed from what you would expect. I'm not an expert for POSIX, but as far as I get it, the basic idea was to express timzones by the combination of their local name and the offset to GMT. An example for middle europe (Central European Time / CET):</p> <pre><code>Europe/Berlin (w/o daylight savings) equals GMT+01:00 equals CET-1 </code></pre> <p><code>GMT-1</code> in the <code>Etc</code> directory in fact describes a (fictous) timezone called "GMT" which is one hour ahead of (the real) GMT.</p> <p>As far as I know, these files are only there to allow you to create (symbolic) links against them, so if you were situated somwhere in middle europe, you would create a link to <code>GMT-1</code> and call it <code>CET-1</code>.</p> <p>The best recommendation I can give you is to entirely ignore the <code>Etc</code> directory and use some mapping table from windows timezone names to unix timezone folders/files. Windows timezone info does not only give the offset to GMT, but also knows about Daylight Savings (and when in begins or ends). The same is true for the folders/files in the timezone database, but not for the files in the <code>Etc</code> directory - they give a simple static offset to GMT.</p> <p>A list of time zones in the tz database can be found <a href="http://en.wikipedia.org/wiki/List_of_tz_database_time_zones" rel="nofollow">in the wikipedia</a>.</p>
