  Hi,

I want know if you have update the new timezone 2016 for Chile, because to 3 weeks ago the chilean goberment has decided change from GMT -03:00 to -04:00 in May 14.

We need create a patche for Red Hat Enterprise Linux 4.

Yes, it was updated. You need to ensure you have the data of the latest tz version (2016c). Red Hat *should* provide that update to their customers. Albeit I don't know their timelines for doing so…

In adittion, we want know if you create time zone database for Windows.

No. Microsoft deals with timezones independently.
