Rudder

The Info of `date +%z` might be also of value, as this specifies the Offset to GMT, which sometimes overlaps with different TZ Names (like WEST and BST).

In fact, we certainly want :

- <RUDDER><TIMEZONE><NAME>CEST...
- <RUDDER><TIMEZONE><OFFSET>+02..

OFFSET is the most important (the one that we will use to display correct time).

Actually:

<RUDDER>
  <TIMEZONE>
    <NAME>blablab</NAME>
    <OFFSET>blabla</OFFSET>
  </TIMEZONE>
...
</RUDDER>

This information is not specific to Rudder, and should thus go in the <OPERATINGSYSTEM> anchor.

• UNIces and UNIX-like systems tend to favor ISO8601 or Olson representations ('+0200', 'CEST', 'Europe/Paris')
• Windows systems have their own representation, as seen in https://msdn.microsoft.com/en-us/library/ms912391(v=winembedded.11).aspx ('Europe/Paris' => 'Romance Standard Time')

What I would propose in this case would be to have a mandatory attribute that contains the derivation from UTC, that is an actual consensus between all systems, and another one that would give the ISO8601 representation, as given by stfrtime %Z:

<TIMEZONE>
    <NAME>CEST</NAME>
    <OFFSET>+0200</OFFSET>
</TIMEZONE>

The NAME would use the Windows format on Windows machines: that is to be expected.
