Package: nanotime 0.3.15.1

nanotime: Nanosecond-Resolution Time Support for R

Full 64-bit resolution date and time functionality with nanosecond granularity is provided, with easy transition to and from the standard 'POSIXct' type. Three additional classes offer interval, period and duration functionality for nanosecond-resolution timestamps.
