Hi Joe,

thanks for your offer. Help is always welcome! The best way to contribute is
to get the latest dev branch of Rmetrics at
https://svn.r-project.org/Rmetrics/trunk/ and test the packages you are used
to work with.

To come back to your remark, there are no real rules for DST because they
can be changed by temporal authorities. the best way is to keep updated with
one of the latest DST database. Actually, we extract data from the zoneinfo
database [http://en.wikipedia.org/wiki/Zoneinfo] and generate DST functions.
So, the function are not hard-coded but auto-generated.

take care,
Y.
