Timezone issue with strftime/strptime and %z and %Z
...strptime("1995-05-25T15:30:00+10:00", format = "%Y-%m-%dT%H:%M:%OS%z")

ISOdate returns incorrect date?
Dear all,
I have found the following (for me) incomprehensible behaviour of
ISOdate (POSIXct):
> ISOdate(1900,6,16)
[1] "1900-06-15 14:00:00 Westeurop?ische Sommerzeit"
> ISOdate(1950,6,16)
[1] "1950-06-16 14:00:00 Westeurop?ische Sommerzeit"
Note that in the first case I get the 15th of June back, not the 16th as
I would have expected!
This happened under R-1.7.1 on both windows and linux.
I would greatly appreciate your comments,
Heiko

Password Hashes
In einer eMail vom 30.08.98 05:55:16 (MEZ) - Mitteleurop. Sommerzeit schreibt

This is nice. Every other user on the system can see that hash with ps. I
would not call that extended security.
