Hi,
Let me know, how to set/unset "isdst" parameter in system/session level.
I could understand the possible values of isdst 0, 1 and -1.
Example:
Sys.setenv(TZ="PST8PDT");
as.POSIXct("2007-11-04 01:00:00");
when I was executed the above command,
LINUX.X64 -> it was treated as PST value.
[1] "2007-11-04 01:00:00 PST"
WINDOWS.X64 -> it was treated as PDT value
[1] "2007-11-04 01:00:00 PDT"
SOLARIS.X64 -> it was treated as PST value.
[1] "2007-11-04 01:00:00 PST"
In 2007 the Daylight saving time was ended at 2007-11-04 02:00:00, so there
was two "2007-11-04 01:00:00" values each for Standard and Daylight time.
But I was not able to understand, how R is displaying the datetime as
PST/PDT.
Please do the needful.
Thanks
Vasanth
