<h2><a name="description">Description</a></h2>
<p>TIMEZONES maps timezones to hour offsets from UTC/GMT
(<EM>Universal Coordinate Time</EM>). The TIMEZONES resource
can be defined only by the
<CODE>TIMEZONES</CODE> element
The format of each line of content is
"<VAR>timezone_acronym</VAR><CODE>:</CODE><VAR>time_offset</VAR>",
where <VAR>time_offset</VAR> is in <tt>[-]HHMM</tt> notation.
Examples of timezone acronyms are: <CODE>UTC</CODE>, <CODE>PDT</CODE>,
<CODE>EST</CODE>. The time offsets should be positive for timezones
West of UTC, and negative for time zones East of UTC. </P>
<table border=0 cellpadding=4>
<tr valign=top>
<td><strong>NOTE</strong></td>
<td><P>Timezone settings in MHonArc are the negative inverse
of what is used in dates in messages. For example, an EST time will
look like the following in a mail message:
</p>
<pre>
Sat, 10 Sep 1994 15:11:10 -0500
</pre>
<p>Notice that <tt>-0500</tt> is used for EST. However, in MHonArc,
EST is mapped to <tt>0500</tt>, since <tt>0500</tt> must be added to
the specified date/time to get the UTC date/time.
</p>
</td>
</tr>
</table>
<P>MHonArc has a default list of timezone acronyms defined with
time offsets. Therefore, the list given in the resource file will
augment the default list. If "<CODE>Override</CODE>" attribute is
specified, any local lists specified in previous <CODE>TIMEZONES</CODE>
elements are replaced.
</P>
<P>Much of the time, the date used by MHonArc has a time
offset instead of a timezone acronym. However, mail messages may
contain timezone acronyms in received/sent dates and MHonArc
must be told what hour offset to add to the give time to get UTC time
to properly sort messages by date. </P>
