I am Sorry for not explained my requirement to you properly.
As you told in Windows I need to update the $R_HOME/share/zoneinfo with the
latest time zone information, since R is not using the operating system
time zone files. Then I have updated the zoneinfo directory, after that it
is working

Hi,
I am working R on windows 2012 R2 platform, I have updated the latest
hotfixes for time zone information(Microsoft KB 2981580.
http://support.microsoft.com/kb/2981580).
But still R is not populating correct date time values(Standard and

R on Windows uses the Olsen timezone database, a copy of which is stored with R
in the Program Files directory (e.g. R/R-3.1.1/share/zoneinfo). You could
update the file yourself if you can find a corrected version, or download an
updated version of R.
Thanks Jeff Newmiller, it is working now.
I would like to know, the same kind of configuration can be done in Linux
and Solaris platform.
Instead of R is mapping to operating system(/usr/share/. /usr/share/lib/)
zoneinfo directory.
Thanks

AFAIK on *NIX systems R uses the OS installation of the Olsen database, so on a
fresh login R should pick up any OS update you have installed.

Do you care about local topography/terrain? I think most of the
calculators/tables that are commonly used assume that you are at a
fairly flat place on the earth's surface, but that is not always true.

hi there,
