One thing to remember about POSIXct is that with floating point you only have 
about 15 digits of accuracy.   With 1970 as the base year there are about 12 
digits used to get seconds so you only have 3 digits for the subseconds so 
milliseconds is the limit.

I've met the  same problem which caused by the POSIXct. I think POSIXlt's
storage is wasting a lot of space  and R should support  the intraday time
handling.  Thank you for your useful comments,  I am reading the
StackOverflow.

As for the "Windows could not handle more than milli-second datetimes and
Linux "almost" micros",  this is decided by the OS standard,  not caused by
other thing.  And so,  I think millisecond is enough for me.
