:mrdocs:

Write the fraction of a second from the timeCache to `d_out`, where the `precision` is the number of digits of precision wanted. Use `decimalChar` (expected to be '.' or ',') as a decimal point, and if `precision == 0` output nothing. If `6 < precision`, write '0' characters following the first 6 digits. The behavior is undefined unless `0 <= millisecond < 1000`, `0 <= microsecond < 1000`, and `0 <= precision`.
