//| The `time` module is a strict subset of the CPython `time` module. So, code
//| written in MicroPython will work in CPython but not necessarily the other
//| way around.
//|
//| .. method:: monotonic()
//|
//|   Returns an always increasing value of time with an unknown reference
//|   point. Only use it to compare against other values from `monotonic`.
//|
//|   :return: the current monotonic time
//|   :rtype: float
//|

//| .. method:: sleep(seconds)
//|
//|   Sleep for a given number of seconds.
