You can use strptime to specify the format of the date and time you want, e.g.
> x1<-strptime(x, "%Y-%m-%d %H:%M:%S") > x1 [1] "2010-04-02 12:00:05" > str(x1) POSIXlt[1:1], format: "2010-04-02 12:00:05" On Wed, Jul 21, 2010 at 8:02 AM, Aaditya Nanduri <aaditya.nand...@gmail.com> wrote: > Ms. Chisholm, > > If you could tell us how you plan to use the variables, we will have a > better understanding of what you are looking for and will be able to help > you. > Are you looking for the time in seconds?
