<DIV><FONT size=2>Srini - I have found it necessary to take exactly this
approach, incorporating one "snapshot" of the TZ data into our product itself so
that it would work properly everywhere. (our web application takes local time
from the user's computer, but requires explicit (or implicit) selection of the
timezone in effect for each entity to which a timezone applies.)</FONT></DIV>

<DIV><FONT face=Arial size=2><SPAN class=749444216-09022001>The TZ
(zoneinfo) database comes installed with several operating
</SPAN></FONT></DIV>
<DIV><FONT face=Arial size=2><SPAN class=749444216-09022001>systems
like Linux, Solaris, etc. </SPAN></FONT></DIV>

<DIV><FONT face=Arial size=2><SPAN class=749444216-09022001>I have noticed the
content</SPAN></FONT><FONT face=Arial size=2><SPAN class=749444216-09022001>
of the TZ database varies between different </SPAN></FONT></DIV>
<DIV><FONT face=Arial size=2><SPAN class=749444216-09022001>versions of the
same</SPAN></FONT><FONT face=Arial size=2><SPAN class=749444216-09022001>
operating system and also between operating </SPAN></FONT></DIV>
<DIV><FONT face=Arial size=2><SPAN class=749444216-09022001>systems.
This could have been because of when a snapshot of the
</SPAN></FONT></DIV>
<DIV><FONT face=Arial size=2><SPAN class=749444216-09022001>TZ database
</SPAN></FONT><FONT face=Arial size=2><SPAN class=749444216-09022001>was
taken. </SPAN></FONT></DIV>

<DIV><FONT face=Arial size=2><SPAN class=749444216-09022001>Ofcourse, one
significant difference is the actual name of the </SPAN></FONT><FONT

face=Arial size=2><SPAN class=749444216-09022001> </SPAN></FONT></DIV>
<DIV><FONT face=Arial size=2><SPAN class=749444216-09022001>Depending on the
content of the TZ database, the time zone </SPAN></FONT><FONT face=Arial
size=2><SPAN class=749444216-09022001>name</SPAN></FONT><FONT face=Arial
size=2><SPAN class=749444216-09022001> look </SPAN></FONT></DIV>
<DIV><FONT face=Arial size=2><SPAN class=749444216-09022001>different.
Is it because the TZ database has evolved? </SPAN></FONT></DIV>

<DIV><FONT face=Arial size=2><SPAN class=749444216-09022001>I also
</SPAN></FONT><FONT face=Arial size=2><SPAN class=749444216-09022001>noticed
that the zone.tab file is not distributed on</SPAN></FONT><FONT face=Arial

<DIV><FONT face=Arial size=2><SPAN

<DIV><FONT face=Arial size=2><SPAN class=749444216-09022001>Now my main

</SPAN></FONT><FONT face=Arial size=2><SPAN class=749444216-09022001>to use an
