Dear list, I'm a bit puzzled by an ambiguity with respect to the representation of micro-/milliseconds when using 'POSIXlt' objects.
It seems that the last digit of the 'sec' attribute sometimes seems to differ from the digits shown when printing the 'POSIXlt' object. You'll find a little SO post with some example code here: http://stackoverflow.com/questions/11725517/ambiguity-with-posixlt-representation-when-microseconds-are-included. In case you don't want to have a look at that, here's another short example: |opts<- options(digits.secs=6) x<- "2012-07-30 12:10:09.123123" posix<- as.POSIXlt(x, tz="Europe/Berlin") > posix [1] "2012-07-30 12:10:09.123122 Europe/Berlin" > posix$sec [1] 9.123123 | # Manually changing the 'sec' attribute |posix$sec<- 9.123122 > posix [1] "2012-07-30 12:10:09.123122 Europe/Berlin" # Still '.123122' posix$sec<- 9.123124 > posix [1] "2012-07-30 12:10:09.123124 Europe/Berlin" # Now it's '.123124' in both 'representations' | Thanks a lot for any clarification on this!
