Dear R People: I'm looking at some data which has the time in seconds since 1992/10/8, 15:15:42.5 Are there any functions currently available to "translate" this or should I just do my own? I figured that I'd check first.

Including correct timezone / daylight saving stuff / leap seconds etc. Best, Uwe Ligges> > Are there any functions currently available to "translate" this or should I > just do my own? > > I figured that I'd check first. > > Thanks, > Erin > >
Your subject line says you want to calculate seconds... the body of your message
says you want to "translate" seconds (to something unspecified).
I am not sure how we are supposed to respond. Can you give us a short example of
what you have and what you want using R syntax?

For going the other way, see ?DateTimeClasses for a lot of information on dates and times, and (probably) ?as.POSIXct for changing something in seconds (as the Examples say, 'a large integer') into a date-time class which you should be able to convert to other things more easily.
