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. -- View this message in context: http://r.789695.n4.nabble.com/Suggestion-on-ITime-class-implementing-tp4662281p4662322.html Sent from the datatable-help mailing list archive at Nabble.com. _______________________________________________ datatable-help mailing list [email protected] https://lists.r-forge.r-project.org/cgi-bin/mailman/listinfo/datatable-help
