Hi R users, I have a maybe small problem which I cannot solve by myself.
I want to convert "chron" "dates" "times" (04/30/06 11:35:00) to a number with as.POSIXct. The Problem is that I can't choose different timezones. I always get "CEST" and not "UTC" what I need. date = as.POSIXct(y,tz="UTC") "2006-04-30 11:35:00 CEST" Then I tried to use as.POSIXlt. date = as.POSIXlt(y,tz="UTC") "2006-04-30 11:35:00 UTC" The advantage is I get time in UTC but now the problem is that I can calculate numbers. date <- as.double(date)/86400 it is not working with as.POSIXlt but with as.POSIXct Thanks!
