Hello, Try
as.POSIXlt(1043107680, origin = "1970-01-01", tz = "CET") Hope this helps, Rui Barradas Em 18-02-2015 17:45, Troels Ring escreveu:
dear friends - sorry to ask another simple question - I have dates set up as this: dates #[1] 2003-01-21 01:08:00 To handle it I did as.POSIXlt(dates) "2003-01-21 01:08:00 CET" but noticed that during write.table it was apparently better to take it further as.numeric(as.POSIXct(as.POSIXlt(dates)) 1043107680 And this works fine for modeling but now I would like to have it back as POSIXlt as.POSIXlt requires an origin, if I'm right. So how is it done?
