Hi all,
I propose multiples of the Planck time, 5.39 × 10 ^−44 s. Unlikely computers can be more accurate than that anytime soon.
On a more serious note, I am not sure what problem was solved by moving from double to a fixed-precision format.
I do know that it now introduced the issue of finding the correct base unit of the fixed-precision format.
From Victor's original message, describing the current functions using 64-bit binary floating point numbers (aka double). They lose precision: "The problem is that Python returns time as a floatting point number which is usually a 64-bit binary floatting number (in the IEEE 754 format). This type starts to loose nanoseconds after 104 days." Eric.
