R issue with rounding milliseconds

Question

Given the following issue with rounding milliseconds under R. How do I get around it so that the times are correct?

> options(digits.secs=3)
> as.POSI         


        

Answer 1

The milliseconds are there:

 unclass(as.POSIXlt("13:29:56.061", '%H:%M:%OS', tz='UTC'))
 $sec
 [1] 56.061
 ...

(There's no need to call format here, it's the name of an argument not the required input from some other function).

Otherwise, I cannot reproduce (on Windows 64-bit R 2.15.0):

options(digits.secs = 3)
as.POSIXlt("13:29:56.061", '%H:%M:%OS', tz='UTC')
[1] "2012-06-07 13:29:56.061 UTC"
