Format a time in picoseconds. This function converts a numeric picosecond value into a human-readable string with units like ps, ns, us, ms, s, m, h, or d.
Given a time in picoseconds, returns a human-readable time value and unit indicator. Resulting unit is dependent on the length of the argument, and can be:
ps - picoseconds
ns - nanoseconds
us - microseconds
ms - milliseconds
With the exception of results under one nanosecond, which are not rounded and are represented as whole numbers, the result is rounded to 2 decimal places, with a minimum of 3 significant digits.
Returns NULL if the argument is NULL.
This function is very similar to the function, but with the following differences:
Represents minutes as min rather than m.
Does not represent weeks.
