You may also find the package "lutz" to be of interest, although that may
be overkill for your needs.
(found by an internet search).

Cheers,

Re: [R] Timezone question

[Marc Schwartz via R-help]

Hi Dennis,

I believe that it may be as simple as:

> format(Sys.time(), "%z")
[1] "-0400"

Where "%z" returns the offset from UTC as a character vector, and where I am in:

> Sys.timezone()
[1] "America/New_York"

There may be some subtleties, and I would suggest reading the relevant help 
files for ?strptime and the above two functions.

Regards,

Marc Schwartz

Is there a simple way to determine the timezone offset for my present location. 
For example, during standard time in the US, the offset from GMT is 8 hours in 
California.

Colleagues

Is there a simple way to determine the timezone offset for my present location. 
 For example, during standard time in the US, the offset from GMT is 8 hours in 
California.
