Can you just use the DateTime type in Julia? http://julia.readthedocs.org/en/latest/stdlib/dates/
This is in the development version of Julia. For a backwards-compatible implementation for Julia 0.3, see: https://github.com/quinnj/Dates.jl If the DateTime type isn't suitable (for example, millisecond resolution), you could possibly inherit from suitable types and still get more features than you currently have.
