I'm wondering how it is implemented and if I can trust it. My doubts come from Python, which clearly documents its difficulties and limitations with time:

] | Well as for the implementation, `time.Now()` falls back to a function implemented in the runtime.
You can review the [C time implementation](http://code.google.com/p/go/source/browse/src/pkg/runtime/time.goc) and the implementation for [`time·now` in assembly](http://code.google.com/p/go/source/browse/src/pkg/runtime/... | One of the problems with Python's [time.time](http://docs.python.org/2/library/time.html#time.time) function is that it returns a [float](http://docs.python.org/2/library/functions.html#float). A float is an [IEEE 754 double-precision number](http://en.wikipedia.org/wiki/Double-precision_floating-point_format) which ha... |
