<DIV><FONT face=Arial><FONT size=2>The new version of Chronos for Squeak, unlike
the version initially published, can be safely installed by file-in. Also
unlike the initial version, it can read reference data from the file
system--especially including time zone rulesets. It can also persist reference
data in the local file system. The Chronos Time Zone Compiler can be installed,
and it can be used to compile Chronos time zone rule files from the Olson
zoneinfo source files.</FONT></FONT></DIV>
<DIV> </DIV>
<DIV><FONT face=Arial><FONT size=2>However, the current Squeak version still
does not have all the functionality of the VisualWorks version. Here's
what's still missing:</FONT></FONT></DIV>
<DIV> </DIV>
<DIV><FONT face=Arial><FONT size=2>* Determination of the host system time zone
(this would require new primitives or FFI function libraries--and is something
that is not at all on my to-do list)</FONT></FONT></DIV>
<DIV> </DIV>
<DIV><FONT face=Arial><FONT size=2>* Support for any Locale other than #en_US--I
may (or may not) decide to use the data published by the Common Locale Data
Repository (CLDR) Project to provide such functionality for Squeak (and for
other Smalltalk implementations as well,) but that won't happen for many months
yet, if it happens at all [ref: <A
href="http://www.unicode.org/cldr/">http://www.unicode.org/cldr/</A>]</FONT></FONT></DIV>
<DIV> </DIV>
<DIV><FONT face=Arial><FONT size=2>* Convenience methods implemented in Squeak
classes that leverage Chronos (e.g., String>>asTimezone,
Number>>hours, etc.)--the issue here, of course, is interference with the
native Chronology library's own such convenience methods (Note: Implementing
such convenience methods for Chronos is the sole responsibility of the Squeak
community)</FONT></FONT></DIV>
<DIV> </DIV>
<DIV><FONT face=Arial><FONT size=2>* Type-compatibility of Chronos classes with
the analogous Chronology classes (Note: Implementing such type-compatibility
methods for Chronos (or Chronos-compatibility for Chronology, for that matter)
is the sole responsibility of the Squeak community)</FONT></FONT></DIV>
